Oldham MX 62 Gas Detection Control Unit

MX 62

An attractive solution for gas and flame detection needs, the MX 62 is a modular and flexible controller that is easy to install and reduces operational costs.

The MX 62 system meets the requirements of ATEX 100 A and offers the high level of security required by SK2 and SIL3 rated systems.

Cost Effective and Secure Installation

The structure of the MX 62 system has been developed to provide redundancy. Reliable data is passed quickly from the detectors to the relays.

Structured programming

The ConfigPro.exe software configures the MX 62 through a secure, password protected interface.
