2200-016 GMA 200-MT16/16 GMA 200 Controller, Configured for 16 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.

2313003-1 2 GMA 313 & GMA 313EQ Stand-Alone System, Complete Set with External Alarm/Reset by GfG

State of the Art Technology

The best solution for CO2 monitoring fromthe specialists in gas detection. The GMA 313 indicates a gas hazard immediately and reliably. The built-in alarm LED and loud horn provide a warning before entering the room. The external alarm GMA 313 EQ also gives a warning wherever you want it, e.g. at the stairway or at the bar. The GMA 313 offers state-of-the-art sensor and microprocessor technology from a compact unit.

The sensor and electronics, horn and lights are integrated in one enclosure, thus saving installation costs. The robust casing is splashwater proof (IP 54), so splash-water cannot enter and damage the monitor. Thermostat control and temperature compensation of the sensor ensure reliable measurements and safety even in case of sudden temperature changes.

Low Maintenance and Long Lifetime

The infrared (NDIR) sensor has a considerably longer lifetime than an electrochemical CO2 sensor. The GMA 313 is low maintenance, robust, and reliable. Installation of the GMA 313 is very simple, just plug it into a standard 110 v ac wall outlet.

Infrared Principle

Carbon dioxide (CO2) absorbs light in the infrared range of the spectral. The NDIR technology of GfG's sensor detects the carbon dioxide concentration precisely and reliably. The infrared light emitted by a lamp passes through the gas sample. Carbon Dioxide absorbs the light in a narrow spectral range.

The remaining light is measured at the detector. The difference between emitted and detected light is proportional to the gas concentration. Water vapor and other gases, which may be presenting the sensor chamber, do not affect the light absorption in this spectral range.

Safe detection results, even with temperature changes. Precise optical measurement ensures the best accuracy and repeatability. The IR principle is as distinct as a fingerprint in criminology.

This means that only carbon dioxide is detected, thus eliminating false alarms from interfering gases. GfG Products use electronics with voltage stabilization and temperature compensation.

This results in stable measurement vales even with considerable temperature variations.

The GMA 313 has no moving parts which could be subject to wear and tear. This ensures a long lifetime and reduced service requirements. Permanent self-check of functional capability provides additional safety. Sensor and electronics are protected by a robust enclosure (IP 54).

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.

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 DAprovides 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.
