MX32 gas controller (up to 8 transmitters)

The MX32 gas controller

3 available versions

The MX32 gas controller is available in 3 versions to meet the greatest number of applications:

• MX32-1: Version 1 4-20 mA analog sensor or up to 4 digital sensors on the same line
• MX32-2: Version 2 4-20 mA analog sensors or up to 8 digital sensors distributed on 2 lines
• MX32-3: Version 2 Wheatstone bridge sensors OLC10 / 100 series for explosive gases detection only

Numerous modules for great flexibility

The Oldham MX32 controller accepts various modules to increase the system's capacities and flexibility.

• Addressable module with 8 analog inputs able to receive all types of 4-20 mA analog gas transmitters
• 4 or 8 relays addressable module (+ 2 logic inputs) that can be deported as close as possible to the controls.
• Addressable module with 16 digital inputs that can receive all digital information (emergency stop, limit switch, fire alarm).
• Addressable module with 4 analog outputs for connection to a recorder, a PLC, a building management system, etc.

MX32 gas controller main assets

• Up to 8 digital or analog gas detectors
• Large graphic LCD display and customizable views
