Flexible meets Powerful. The GasMark M255 gas detection control panel.

The M255 can interface to, but operate independently of plant control systems for a reliable stand- alone safety system. The M255 comes standard with four Modbus channels with a capacity of 255 devices, eight analog input channels, and eight onboard relays, user programmable to trigger upon any event for any sensor or group of sensors.

The 10" color touchscreen displays real- time status of gas detector concentrations and alarms, and allows for easier programming via a user- friendly menu system. A USB port allows for easy field software updates, provides a means to backup system programming, and allows for datalogging downloads.

The M- XM expansion modules are intended to provide users with options to increase the number of analog and discrete inputs and relay and analog outputs for the M255 controller. All modules allow an operator to monitor and/or control connected devices from the M255. This modular design provides users with the ability to tailor the network to the unique needs of their facility.

Applications
  • Food Processing areas
  • Refrigeration Systems
  • Chemical Plants
  • Cold Storage
  • Parking Garages
  • Perimeter Monitoring
  • Compressor Rooms
  • Sea Vessels
  • Warehouses.
Benefits Applications
  • Versatile for any application
  • RS-485 daisy-chain cuts cable installation cost by up to 50%
  • Remote I/O option with the M-XM expansion modules
  • Easy programming from touchscreen

Out of the box, the M255 is configured with default setpoints loaded in the software. Easily enter the zone location names and adjust alarm setpoints as necessary.

The onboard power supply is large enough to power most connected detectors and external 24 VDC horn/ strobes. For larger systems, additional power supplies can be installed along the bus when needed.
