Oldham MX43 Analogue and Digital Gas Controller

Oldham MX 43 Gas Detection Controller

The Oldham MX 43 is a fully scalable gas detection controller designed to continuously monitor and control gas hazards in industrial and commercial environments. Supporting both analogue and digital gas detectors, the MX 43 provides a flexible solution for systems ranging from a few monitoring points to larger installations with up to 32 gas detectors.

Thanks to its modular design, engineers can easily expand or adapt the system as monitoring requirements change. Furthermore, the MX 43 complies with Functional Safety Performance Level 1 requirements, helping operators maintain reliable protection against combustible, toxic, and oxygen-related gas hazards.

In addition, the controller features an intuitive user interface with a large backlit display, multilingual menus, and clear status indicators, making day-to-day operation and maintenance simple and efficient. The integrated RS-485 Modbus communication also allows seamless integration with SCADA and Building Management Systems (BMS).
