2200-014 GMA 200-MT16/14 GMA 200 Controller, Configured for 14 Measuring Points by GfG

For more than 50 years, the key goal of GfG has been to meet the highest demands of occupational health and safety, industrial equipment reliability and environmental protection. This goal has been reached by developing innovative and reliable gas warning systems. Development of the new GMA 200 gas warning system satisfies these requirements while taking into account suitability testing in line with ATEX Directive 94/9/EC. If switching functions for explosion protection are required, the GMA 200 gas warning system is the optimal solution. It also meets the requirements for gas warning systems without necessary ATEX certification and functional safety requirements (SIL).

Design of the GMA 200 gas warning system

The design of the GMA 200 gas warning system ensures flexible and simple operation in industrial and commercial applications for measuring combustible and toxic gases / vapors, and for measuring oxygen concentrations. The compact design of the GMA 200 as a DIN rail module enables cost-effective and space-saving installation.

Modular design of the GMA 200 MT6 / MT16 gas warning system

Up to 16 detectors can be connected to the GMA 200 gas warning system. A software program enables the quick and easy configuration of the measuring points for already installed GMA 200 gas warning systems. Measuring point designations, the detector type, the type of gas and measuring range as well as three individual or specified alarm thresholds can be programmed for each measuring point using the configuration software. A microprocessor evaluates the analog input signals of the connected detectors.

Integrated relays

As a result of the increasing requirements being placed on safety measures, even redundant protection against gas hazards, complex gas warning systems are in demand. The GMA 200 gas warning system is equipped with 8 internal relays. 6 relays can be freely configured using the software program in order to implement safety measures and alarms. The configuration software offers numerous and flexible options, such as the assignment of one or several measuring points to relays, single alarms per measuring point and alarm threshold, configuration of collective or group alarms and fault messages and voting functions. Two further relays are available for safety-related fault messages and for maintenance.

Relay modules

Using a GMA RT relay module, it is possible to extend the GMA 200 gas warning system by 16 additional freely configurable relays. A total of 4 additional relay modules and thus 64 additional relays can be managed via the GMA 200 gas warning system. Digital connection of the GMA RT relay module to the GMA 200 gas warning system enables the local positioning of the relay modules. The local and thus flexible installation of the relay modules results in large cost savings due to reduced cabling and assembly functions.

Availability of the gas warning system

Besides the traditional voltage supply, the GMA 200 gas warning system can also be operated with a redundant, safety-related voltage supply and therefore meets the highest demands of functional safety and the required permanent availability of gas warning systems for detecting potential gas hazards.

System functions: LED displays

The status of the GMA 200 gas warning system operation, fault, service is shown via LEDs.

Graphical display

The clearly structured layout of the GMA 200 gas warning system enables the quick detection of hazardous situations. Currently measured values are permanently displayed on the LCD graphical display. In the event of gas alarms, the display lighting is automatically activated with a red background.

Additionally, the LED display for Alarm 1, Alarm 2, Alarm 3 is shown. In the event of an alarm, the status of the active relays 1-8 is displayed simultaneously via LEDs.

The integrated memory enables the reading of alarm levels and minimum / maximum values per measuring point at the LCD for an initial, quick hazard assessment.

Data logger function

The GMA 200 gas warning system can be equipped with a micro SD card for saving the measured values. The measured values, mean values, alarm events and faults are permanently stored at individually configurable intervals, and can be read out for evaluation.

Operation via keyboard

Five buttons enable operation at the GMA 200 gas warning system. The main functions of the keyboard are the acknowledgement of alarms and the menu-driven operation. Information on the status of the gas warning system, detector and the relays can be retrieved in the operating menu.

Configuration

A USB port at the GMA 200 gas warning system can be used for connection to the configuration software.

Features

• A variety of transmitters can be connected for measurement of combustible, toxic gases/vapors and oxygen
• Multiple relay configurations
• Flexible, reliable and economic

2492-025 Dynagard 25 for CO2 Stand-Alone System with IR 24 Transmitter for Detecting Carbon Dioxide (CO2) from 0-25% vol. and GMA 41B Single Channel Controller by GfG

Simple and Effective

The Dynagard 25 Series accurately measures CO2 levels. The unit offers a local display, a horn / strobe, and a linear 4-20 mA output. The Dynagard 25 Series offers a safe and reliable gas warning system.

Alarm Points

Each alarm can be adjusted separately. The alarm point values can be freely adjusted within the detection range of the transmitter. Every alarm point value can be set to over range / under range, latching / non-latching, or resettable / non-resettable.

Alarm Relays

The controller provides four voltage-free relays for the three alarms and one fault warning. The relays may be used to control additional alarm devices like lights or horns. They can even prompt specific counter measures to prevent or limit dangers from gases or vapors.

IR 24 Detection Principle: Infrared Light

Since carbon dioxide (CO2) absorbs light in the infrared spectral range, the NDIR method used in the GfG sensor can measure the carbon dioxide concentration precisely and reliably. Infrared light is sent through the sensor chamber. Carbon dioxide absorbs a part of this light in a narrow spectral range, and the remaining light is measured at the detector. The difference between the light sent and received is proportional to the gas concentration. Water vapor or other gases that can be present in the sensor chamber do not affect the light absorption in this spectrum band.

Features

• Easy installation
• Local display and horn / strobe
• Adjustable alarm points
• On-board relays for external controls
• 4-20 mA output

2811-713-001M EC 28 Gas Transmitter with MODBUS, Ethylene Oxide (C2H4O), No Display by GfG

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.
