Entête

The multi-gas controller for the detection of toxic, combustible and hazardous gases in industrial environments.

The PolyGard®2 MGC2-K controller is designed to detect and alert to toxic and/or explosive atmospheres. It is directly connected to a low-voltage power supply in accordance with standard EN 50 082. It displays the measured values and activates the alarm relays if the alarm setpoints are exceeded.

It is designed to work with up to 11 sensors:

  • Three analogue sensors with a 4-20mA signal
  • Eight digital sensors

Equipped with the RS-485 MODBUS protocol, the Sensepoint XCL and XRL can be distributed along a digital line, which reduces installation costs.

The MGC2 controller complies with SIL2-certified development processes for the use of 4-20mA signal inputs/outputs.

Applications with Sensepoint XRL: waste water, power plants, vehicles, laboratories, and the food & beverage industry

Applications with Sensepoint XCL: hospitals, boiler rooms, transportation, parking garages and laboratories.
