The GMA 200-MT can control up to 16 individual gas transmitters (sensors) and it is possible to extend the GMA 200 controller by 16 additional freely configurable relays.

• Complete controller package available in 4 to 16 channel configurations
• Up to 16 analog inputs or 16 digital inputs
• Scalable system with fully programmable menu driven relays
• NEMA 4X housing
• Local display, stack light horn and strobe
• Terminal blocks for easy termination
• Power supply

Inputs:
16 Analog inputs: (4 to 20 mA or 0.2 to 1 mA); max. 50 Ohm input resistance.
Two digital inputs: acknowledgement of alarms can be freely configured.
2X RS485 BUS: for connection of external relay modules or digital transmitters in BUS wiring.
1X RS485 BUS: for digital transfer of measured and output data to a higher-level control centre or with master functionality of a GMA 200-MT for the connection of GMA 200-RT relay modules.

The clearly structured layout with graphical display enables the quick detection of hazardous situations. Currently measured values are displayed on the LCD graphical display.
