2200-092 GMA 200-MW4/2 Controller, Configured for 2 Measuring Points, Supply Voltage, 110 V AC, with Internal Power Supply by GfG

The GMA 200 offers innovative technology and trend-setting flexibility. It is designed for commercial and industrial applications for the measurement of combustible and toxic gases as well as for the measurement of oxygen. The compact construction of the GMA 200-MW4 provides a cost-efficient solution for safe gas monitoring of small facilities.

Parallel measurement and flexible application

With the GMA 200-MW4 up to four different transmitters can be monitored simultaneously. They can be connected analog or digital to the GMA 200-MW4. Using the configuration software for every connected single transmitter the measurement range, the measurement designation, the type of transmitter and the type of gas can be set individually and three alarm thresholds can be programmed. The microprocessor of the GMA 200-MW4 evaluates all receiving signals and activates alarm or relays. In doing so one single GMA 200-MW4 can master different gas detection tasks.

Integrated relays

GMA 200-MW systems include comprehensive and fully programmable relays. Each GMA 200-MW4 controller is equipped with six internal relays. For the implementation of safety measures and alarm, four relays can be freely programmed so that in case of alarm the safety measures can be triggered automatically.

The programming grants wide-ranged and flexible possibilities such as the allocation of one or more measurement points to relay, single alarm per measurement point, configuration of collective alarm and group alarm, error report and voting function. For each, safety related error report and and maintenance, there is one additional relay available.

Relay modules

The GMA 200-RT relay module can be added and adds an additional 16 freely configurable relays. A total of four additional relay modules (for 64 additional relays) can be managed by the same GMA 200-MW4. Digital interface (RS485) with the GMA 200-RT relay module allows decentralized installation of the relay modules, which offers great flexibility and reduces cabling and installation costs.

GMA 200-MW4 Controller

In addition to the traditional power supply the GMA 200-MW4 can be operated with a redundant, safety-oriented power supply. Based on this the GMA 200-MW4 meets the highest safety requirements and guaranties a permanent availability of gas detection systems for potential gas hazards.

LED indicator lights

LEDs show the Status of the GMA 200-MW4 controller (including operation, fault, service alarm and relay status).

Graphical display

Currently measured values are displayed on a backlit, graphical LCD. In the event of an alarm the display changes color from green to red, and highlights the affected channels. Furthermore the display of alarm 1, alarm 2 and alarm 3 occurs on the LED graphic display. Simultaneously the status of the affected channels 1-8 is shown by the LED lamps in the case of alarm.

The integrated storage allows the reading of alarm stages.

Datalogging standard

Measured values, mean values, alarm events and faults are permanently stored on a microSD memory card.

Operation via keypad

Operation of the GMA 200-MW4 is through easy-to-use menus, and a simple five button interface. Main functions of the keypad are the alarm acknowledgement, and viewing information on the status of the controller, the transmitter and the relays through the operation menu.

Configuration

A built-in USB port in the GMA 200-MW4 is used for connection to the configuration software.

GMA 200 bus interfaces (RS485)

There are three RS485 interfaces on the GMA 200-MW systems.

2 x TRM - BUS

The TRM-BUS allows the connection of up to 16 digital Transmitters. They can be connected in loop structure or line structure to the GMA 200, so that there is a wide range of possible connections. In addition, every TRM - BUS offers integration of the external relay module GMA 200-RT / RTD.

1 x GMA - BUS

In addition to the option to use this BUS for the connection of an external relay module, this interface also offers the option to integrate the GMA 200 controller into a network of facilities. A Modbus protocol in the RTU - Mode, which is transmitted through the GMA - BUS interface allows status readings of the GMA 200 controller by using a PC. Additional gateways are offered by GfG and enable the digital status monitoring and data processing using additional external modules (e.g. PLC).

GMA 200 Visualization

Complex Gas Detection Systems with several controllers and numerous different transmitters call for a clear overview to guarantee safety. The rapid and precise localization of gas hazards is critical to protect facilities, environment and human life. The PC - based Visualization Software, GMA 200 clearly displays the status of the entire Gas Detection System. If any alarm threshold is exceeded, the alarm triggers a measuring station with associated designation, the measured value, the measured unit (% vol. or % LEL) and the type of gas is displayed immediately on the screen, so that appropriate measures can be taken quickly.

Advanced Technology

Wherever hazards are expected, the EC 28 transmitter and GfG's proven monitoring systems are the right choice for reliable surveillance. The ATEX-certified design, an integrated, Ex-proof buzzer, and bright alarm LEDs provide the highest safety in hazardous areas by including visual and audible alarms. The gas alarm not only alerts the person in the control room of hazards, but also the person on-site.

Easy handling

Smart sensor technology allows a user to install the transmitter or to replace a sensor within a few seconds - just plug the sensor into the transmitter. Adjustments are done directly at the transmitter using touch keys or with the remote control (one-person calibration).

Remote Control RC2

Ammonia and hydrogen are lighter than air. With the transmitter installed close to the ceiling, GfG can provide permanently connected cables with plugs for the remote control, which allow the user to do all adjustments without having to climb a ladder. In addition, one remote control can be used for several transmitters, which helps cut costs and increase efficiency.

The remote control display is always identical to that of the transmitter, making inspection, service, and calibration considerably simple.

The remote control reads the current gas concentration and can be used as an external display.

Integrated Alarm - Saves Money on Ex-proof Alarm and Wiring!

The EC 28 D model shows the current gas concentration on-site at the display of the transmitter and also at GfG's GMA controller.

The EC 28 DA provides additional bright alarm LEDs and a buzzer - avoiding costs for a separate Ex-proof horn and an Ex-proof light. You also save money on wiring to connect the controller and alarm devices.

In combination with GfG's flexible control units, the EC 28 provides various possibilities for reliable and cost-effective gas monitoring.

301C24-DLC-BIP 301C Controller with Datalogger, BACnet/IP Output, ABS Polycarbonate Enclosure, Title 24 Compliant by Honeywell Analytics

Designed for simple installation and operation, the 301C continuously monitors and controls toxic gases, combustible gases and oxygen hazards.

Product Overview:

Using an addressable RS-485 Modbus communication protocol, the 301C uses daisy chain wiring requiring only 2 pairs of wires to connect up to 96 transmitters on the 3 input channels. This simplifies installation, in turn lowering costs. The 301C's zoning and averaging abilities significantly reduce operational and maintenance costs.

Zoning / Averaging:

The 301C controller offers unique zoning capabilities which permit the averaging and comparison of multiple sensor readings. Zoning can reduce operational costs by ensuring that localized brief fluctuations registered at a single transmitter do not activate relays. For example, a car idling in a parking structure may locally increase a reading at a nearby transmitter. Rather than activating a fan as a result of the temporary localized fluctuation, zoning can be used to limit relay activation until the average reading for a zone exceeds a set-point. This can reduce run time of fans, yielding savings in both energy usage and wear and tear. The 301C has the capacity to manage input from three Modbus channels for up to 96 transmitters and up to 50 wireless transmitters that can be associated with up to 126 zones. Transmitters can belong to an unlimited number of zones, providing maximum operational and control flexibility.

3300-32-014 CC 33 Fixed Transmitter with Methanol (CH4O), Stainless Steel Housing, 0-100% LEL (MK 208-3), RS 485 with Relay by GfG

It has always been our aspiration to combine innovative ideas and technology with functional design. This is how quality and longevity come about. Attributes symbolic of the name GfG in gas measurement.

Are you looking for an innovative transmitter for flammable gases, but need explosion protection? Then a transmitter from the GfG 33 series is the right choice.

Robust housing for every application

The transmitters of the 33 series are flameproof encapsulated and fulfill the requirements of the type of protection "d". Depending on the application, you can choose the 33 transmitter with an epoxy-based aluminum or a pure stainless steel housing. In order to meet the quality requirements of our customers and our own standards in terms of durability, we use a particularly high-quality and durable Viton seal in the 33 series. This can withstand even the toughest operating conditions for many years.

Variants

GfG offers the CC 33 in two variants:

For conventional industrial The CC 33 is available in a lacquered die-cast aluminum housing with 10mm thick bulletproof glass. Applications with special conditions such as e.g. in the Food industry can be covered by a unpainted housing made of stainless steel with a 15mm thick bulletproof glass.

Operation by means of magnetic pin

The three magnetic switches behind the protective glass, which is up to 15mm thick, can be operated using the GfG magnetic pin. The GfG typical three-button operation is easy to understand. The menu is clearly structured and logically structured.

All transmitters of the 22, 29 and 33 series have a uniform user interface. The uniform operation and the logical system structure keep your training and maintenance effort as low as possible.

Proven and innovative is not a contradiction

The CC 33 works on the principle of catalytic heat generation (WT), a proven method for measuring combustible gases. The transmitters are equipped with high-performance electronics for voltage stabilization, processing of measured value output and temperature compensation. The long life of the sensors minimizes follow-up costs.

Sensor technology

With improved sensor technology and the unique GfG "chimney effect", the CC 33 transmitter for combustible gases has one of the fastest response times in the world. There are more crucial seconds left to initiate countermeasures and to bring people to safety.

Universal signal transmission

The measured values and status displays of the 33 series can be transmitted either analog or digital via the Modbus interface. Due to the different variants of signal transmission, a transmitter of the 33 series can be connected to almost any gas warning system as an additional measuring point or in exchange for existing transducers.

Signal processing

The embedded software of the 33 transmitter linearises the measurement signal and compensates for temperature influences. As a result, correct measured values are transmitted even in the event of weather-related temperature fluctuations. The execution of the software enables the detection of faults and, in the Modbus variant, the requirement of required service or maintenance work.

Smart sensors

Pre-calibrated sensor modules can be screwed directly into the sensor receptacle on the housing of the CC 33. The smart GfG sensors are pre-programmed with all the necessary parameters and can be used without much effort ("plug and play"). Sensor changes are shown in the display. (catalytic and electrochemical sensors)

Three freely programmable internal relays

The 33er transmitters can be used as a "stand-alone system". You can set the two alarm thresholds individually and freely program the optional three relays. You do not need a cable to a controller and you can nevertheless reliably switch safety-related devices.

With colored graphic display

The clearly laid-out graphic display makes it easy to read the device status, the current measured value and many other important information. In the event of an alarm, the display turns red. The large LEDs signal from a distance the current device status and thus serve the rapid information of your employees about any alarms or malfunctions.

Using the display, you can easily navigate through the clear device menu and make various settings, including calibration, depending on your user authorization.

Calibration

For regular function control with gas application, a calibration adapter is placed on the transmitter to ensure a safe and even gas supply.
