Control system GMA40

Simple installation and control
The GMA40 system is a flexible, cost-effective control systems for DIN-rail mounting. The controllers can be clipped directly on to standard DIN rails in switchgear cabinets. As many controllers as required can be plugged together, so that voltage supply and alarms can be connected without additional wiring.

GMA40 series versions

GMA41 for 1 transmitter, for the control of 1 measuring point (1-channel). With LED display, 3 alarms, relays and 4-20mA output.
...B with integrated bus system for transmission of alarm and failure reports.
...EC with integrated power pack for the operation of electro-chemical transmitters.
...ECB for electronic transmitters, with bus system and power pack.

Reliable and cost-effective
Together with the appropriate transmitters, GMA40 series controllers provide a complete fixed gas detection system for a wide range of different flammable and toxic gases, and oxygen. All transmitter types can be attached. The GMA40 series controllers supply the attached transmitters with power and process input signals received.

Flexible applications
Three alarm thresholds can be individually adjusted in the GMA40 series controllers. In addition, each controller has four floating relays which can be switched normally open or closed. These relays can activate external alarm devices, or switch on ventilation, for example. Gas leaks are rapidly detected.

Fast reading of measured values
The 3-digit LED display provides a constant reading of gas concentration. Measuring range and gas type can also be displayed simply from a button push.
Zero adjustment and adjustment are simply done via push buttons. With the max/min memory the gas concentration can be accurately recorded after an alarm. The highest or lowest measured value is stored and displayed on the LED display. A 4-20mA output (GMA41) means the transmitter signal can be forwarded to other control or recording equipment.
