2200-RT GMA 200-RT Relay Module without Display, 16 Relay (Change Over Contact) 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 controller 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 controller is the optimal solution. It also meets the requirements for gas warning systems in non-hazardous locations.

The GMA 200-RT / RTD Relay modules

Using a GMA 200-RT / RTD relay module, it is possible to extend the GMA 200 controller by 16 additional freely configurable relays. A total of 4 additional relay modules and thus 64 additional relays can be managed through the GMA 200 controller. Digital connection of the GMA RT / RTD relay module to the GMA 200 controller enables the local positioning of the relay modules. This local installation of the relay module results in significant cost savings through reduced cabling and installation costs.

GMA 200-RTD Graphical display

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

Operation via keyboard on the GMA 200- RTD display

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

4100-DP GMA 4100-DP Dew Point Monitor by GfG

The GMA 4100-DP continuously provides information on the measured dew point level, exceeded alarm thresholds and its operational status. As soon as the dew point exceeds one of the three pre-set levels, the GMA 4100-DP gives a warning by means of the LED display, the console mounted horn/strobe, and controls the relevant alarm relays. In addition to this, the GMA 4100-DP provides the measurement value as an analog output signal for further evaluation. The GMA 4100-DP is easy to operate and maintenance-free. The dew point sensor is self calibrating and lasts for years. Should unexpected failures or system faults occur, the comprehensive failure recognition allows a quick and specific service.

Alarm points

Each alarm can be adjusted separately. Relay chatter is eliminated with the adjustable alarm delay. The alarm point values can be freely adjusted using the keypads on the controller.
