2200-015 GMA 200-MT16/15 GMA 200 Controller, Configured for 15 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
• Intuitive, backlit graphical LCD with "traffic light function" (green, amber, red)
• SIL certification

400MT-128 GMA400 Controller, 128 Channels with red strobe, 10 amp, 16"x14"x8" by GfG

Fixed gas detection systems, consisting of one or more central controllers and transmitters, are used in applications requiring continuous monitoring of toxic gases, combustible gases and vapors or oxygen. In situations which make standard solutions hit their limits because of the number of monitored measuring points or zones, the GMA400 controller provides new options for creating complex gas detection systems.

Up to 16 analog or 128 digital GfG transmitters can be connected to one GMA400 controller. An additional 32 virtual transmitters monitor calculated parameters, such as mean values, minimum / maximum values and environmental influences. The compact DINrail-mounted controller (T35) is installed in control cabinets or wallmounted housings.

Digital Communication on Analog Lines

ACDC is a patented technology which allows transmitters to communicate information that goes beyond the plain measured value to the central evaluation unit, using 3-wire 4-20mA line that were already in place. It also receives digital signals from the controller in return. This solution is a significant benefit to your system, as it allows you to use existing analog loops for high-speed transmission of digital data.

Using the analog cabling you already had will allow you to significantly reduce the costs of updating your system – while controllers and ACDC-capable transmitters will still be able to communicate like in a digital system.

The benefits of digital communication

• Bidirectional transmission of additional data, such as mean values or status notifications
• Maintenance of transmitters which are difficult to access using remote calibration
• Higher accuracy and immunity to interferences

Up to 16 ACDC-capable transmitters can be connected directly to the ACDC-capable GMA400. The GMA400-AT24 module lets you upgrade that number to 128.
