2200-007 GMA 200-MT16/7 GMA 200 Controller, Configured for 7 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.

IR22-808-D IR 22 Fixed Transmitter with Carbon Dioxide (CO₂) Sensor, 0 - 25% vol. or 0 - 50% vol. Range, Display / 4-20 mA by GfG

The IR 22 transmitter combines the proven infrared measurement method to detect carbon dioxide or combustible gases (HC) with the innovative technique of the new 22 series transmitters. This new GfG transmit- ter generation has been developed and manufactured according to SIL standards.

The comprehensive user menu and the versatile setting options make this transmitter series quite flexible and adaptable to all individual requirements. Precise measurement results at various environmental conditions, as well as the large dynamic measurement range of a few ppm up to 5 % volume CO₂ or 100% LEL.

Time-proven and innovative

The EC 22 is equipped with high quality GfG sensors. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow up costs are minimized thanks to the long lifespan of the sensors.

Signal processing

The transmitter includes the complete electronic system for the signal processing and fail-safe forwarding of the measurement signal to the controller. The embedded software of the IR 22 linearises the measurement signal and compensates for environmental influences.

Therefore, when temperature variations are caused by the weather or changes of the humidity, the measured values will be accurate.

In addition, the transmitter provides the option to transfer service, maintenance and error messages to a connected GfG gas measurement controller. The IR 22 transmitter sends the signals either through an analog 4-20 mA current interface or a digital (RS485) Modbus interface.

Flexibility for any application

The IR 22 transmitter includes the sensor, status LEDs, either an analog or a digital interface, "Zero button" to adjust the zero point, and a test socket and potentiometer for the sensor calibration.

In addition, the IR 22 can be ordered with backlit graphical display. The display shows the current gas concentration, allows access to service functions, enables operation using a membrane keypad and includes optical and acoustical signal transmitters.

Features

• Long service life of the infrared (NDIR) sensor

CS22-716-M CS22 Fixed Transmitter, R-404a, no display, Modbus, 0(30) - 2,000 ppm by GfG

Wherever toxic or flammable gases and vapors must be monitored without requirements for explosion protection, the use of the CS22 is recommended.

Proven and cost-effective

The CS22 works on the principle of chemisorption (CS). Thanks to a wide range of monitorable gases and multiple measurement ranges, the CS22 offers a wide range of uses, from laboratories to industrial applications to refrigeration systems.

Transmitters with electrochemical sensors (EC), are also used with toxic and flammable gases. In contrast, the CS22 is a much more durable and cost-efficient solution. However, the environmental parameters must fit.

Communicates analog and digital

The measured values and status information of the CS22 can be transmitted either analog (4-20 mA or 0.2-1 mA) or digital (RS-485). This allows not only the use in combination with any GfG controller, but also the connection to programmable logic controllers (PLC).

Smart measured value processing

Industry-wide, the trend is towards smart units, such as the CS22, whose integrated electronics process the data already at the measuring point. The linearization of the measurement signal, compensation of temperature influences, detection of malfunctions and information on the next service or maintenance interval are just some of the advantages that result.

Variants for every requirement

The basic version of the CS22 is sufficient for many applications. If a measured value display on site is desired, there is also a variant with display and acoustic alarm.

CS22 Basic variant for a wide range of catalytic sensors
CS22 D with display to show the current measured value

In combination with GfG's powerful controllers, both variants are the right choice for a wide range of gases to be monitored.

The EC 22 is equipped with high quality GfG sensors. The transmitters are fitted with high-performance electronics for voltage stabilization, processing of readings, and temperature compensation. Follow up costs are minimized thanks to the long lifespan of the sensors.

Signal processing

The transmitter includes the complete electronic system for the signal processing and fail-safe forwarding of the measurement signal to the controller. The embedded software of the IR 22 linearises the measurement signal and compensates for environmental influences.

Therefore, when temperature variations are caused by the weather or changes of the humidity, the measured values will be accurate.

In addition, the transmitter provides the option to transfer service, maintenance and error messages to a connected GfG gas measurement controller. The IR 22 transmitter sends the signals either through an analog 4-20 mA current interface or a digital (RS485) Modbus interface.

Flexibility for any application

The IR 22 transmitter includes the sensor, status LEDs, either an analog or a digital interface, "Zero button" to adjust the zero point, and a test socket and potentiometer for the sensor calibration.

In addition, the IR 22 can be ordered with backlit graphical display. The display shows the current gas concentration, allows access to service functions, enables operation using a membrane keypad and includes optical and acoustical signal transmitters.

CS22-707 CS22 Fixed Transmitter, Ammonia (NH3), no display, 4-20 mA, 0(20) - 1% vol. (10,000 ppm) by GfG

Wherever toxic or flammable gases and vapors must be monitored without requirements for explosion protection, the use of the CS22 is recommended.

Proven and cost-effective

The CS22 works on the principle of chemisorption (CS). Thanks to a wide range of monitorable gases and multiple measurement ranges, the CS22 offers a wide range of uses, from laboratories to industrial applications to refrigeration systems.

Transmitters with electrochemical sensors (EC), are also used with toxic and flammable gases. In contrast, the CS22 is a much more durable and cost-efficient solution. However, the environmental parameters must fit.

Communicates analog and digital

The measured values and status information of the CS22 can be transmitted either analog (4-20 mA or 0.2-1 mA) or digital (RS-485). This allows not only the use in combination with any GfG controller, but also the connection to programmable logic controllers (PLC).

Smart measured value processing

Industry-wide, the trend is towards smart units, such as the CS22, whose integrated electronics process the data already at the measuring point. The linearization of the measurement signal, compensation of temperature influences, detection of malfunctions and information on the next service or maintenance interval are just some of the advantages that result.

Variants for every requirement

The basic version of the CS22 is sufficient for many applications. If a measured value display on site is desired, there is also a variant with display and acoustic alarm.
