产品描述:

Complete control systems for wall mounting
Switchgear cabinets or additional housings are not necessary
Together with the appropriate transmitters, GMA80 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 GMA80 series controllers supply the attached transmitters with power and process input signals received.  The controllers support 2- and 3-wire inputs and supply power to the attached transmitters. Multiple measuring points can be monitored at the same time.
GMA80 series versions
GMA81 for 1 transmitter for control of 1 measuring point. 3 adjustable threshold alarms are available.

GMA83 for 3 transmitters (of the same type) for control of up to 3 measuring points. Individual alarms for each transmitter.

GMA84 for 4 transmitters (of the same type) for control of up to 4 measuring points. 3 adjustable threshold alarms as common alarms are available. The channel in alarm can be viewed on the controller display.

GMA88 for 8 transmitters (or two times 4 transmitters of the same type) for control of up to 8 measuring points. 3 adjustable threshold alarms as common alarms are available. The channel in alarm can be viewed on the controller display.

Different versions of the GMA 80 (GMA..A) are available with integrated audible and visual alarms. This reduces the cost for extra wiring and external warning devices.

Flexible applications
Three alarm thresholds can be individually adjusted in the GMA80 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.

The advantages at a glance
Durable housing for simple wall mounting
Choice from 1 to 8 transmitter inputs
Splash-water protected (IP54)
