The Oldham MX 43 by Teledyne is a flexible gas detection system controller continuously monitoring, measuring and controlling gas hazards, conforming to functional safety performance level 1 standard.  The MX 43 gas detector manages both digital lines and analogue channels. Incorporating digital technology allows up to a maximum of 32 detectors to be distributed on eight lines or 16 detectors across four lines.

Featuring a multi-language LCD backlit display, customisable by the user, 1 to 16 channels can be viewed simultaneously. Access to operation menus is by five smart keys, with one audible alarm accept/reset button.

An optional 4GB USB module provides two years of storage or eighteen months for a controller equipped with 32 detectors. Sampling rates can be set by the user from 2 seconds to 15 minutes, recording in real-time of all events (alarms, faults, alarm resets, calibration). The USB allows firmware updates and controller configuration.

Com 43 software enables controller programming, compatible with any MX 43 controllers already in use. Controller parameters are configured on a PC and transferred to the MX 43 using a USB cable. Full functions can be accessed:

  • Configuration of measurement channels
  • Simplified relay programming
  • Up to 5 on-board functions: OR, AND, NOR, NAND, VOTING
  • Advanced management of audible alarms with timer options (holding time, automatic acknowledgement, reactivation, evacuation)

Programming functions

  • Graphic display for easy relay programming
  • Copy-paste function saving time by preventing programming errors from one sensor to the next
  • Verification/validation feature to prevent programming errors
  • Access pre-programmed gas monitor library according to industry standards
