Gas Warning System for 19‘‘ Racks solenoid valves or turning a fan on, they can introduce specic counter measures to prevent dangers from gases or vapours. Every relay can be either a normally closed (NC) or normally open (NO) contact and works in either closed or open circuit operation. This exibility allows the GMA to meet individual requirements and to offer a safe solution for specic gas detection problems. Control modules for up to 4 channels The GMA104 controller allows the user to operate up to 4 transmitters simultaneously. This considerably reduces the cost of a multi-detection...

Decisive Advantage in Safety Not affected by mains failure In case of mains failure the optional battery back-up NAV takes over automatically and without delay. Even in such a critical situation safety remains unaffected. Just slide the NAV into the rack; it does not require additional wiring. Battery Back-Up Everything at a glance A 3-digit LED display indicates the present gas concentration. Depending on the measurement task, the readout is done in ppm, mg/m3, % LEL or Vol.-%. Additional LEDs inform about operational status, alarm or failure. You can easily see all measurement values at a...
