Teledyne Oldham MX 32 Fixed Gas Controller

The Teledyne Oldham MX 32 controller takes both analogue & digital inputs and covers all needs for a wide variety of applications. The MX 32 is a compact, low-profile controller that continuously monitors gas detection and more generally any 4-20 mA, MODBUS RS485 signal from compatible detectors.

Oldham MX 32 Key Features:

Analog and digital controller
Up to eight detectors
Fully scalable
SIL1 reliability

Different modules can be connected to improve the capabilities of the controller.

4 or 8-relay module

Programmable 4 or 8--relay module can be located closer to the actuators for cost saving.

8-analog-input

Can connect standard analog transmitters (gas or flame detectors for instance) on a digital line for cost savings.

16-logic-input module

Addressable module of 16 logic input for recovery of digital information such as fire or intrusion alarms, emergency stop, limit switch activation, etc.

4-analog-output

Addressable 4-analog-output module that delivers four analog 4-20mA signal outputs (detector output copy, min, max,average of a group of detectors) for connection to a datalogger, a PLC, a Building Management System (BMS), etc.
