MX43 Gas Detection Controller

The MX 43 gas detector manages both digital lines and analog channels, and covers all needs for a wide variety of gas monitoring applications.

SIL1 Certified MX 43 is a Flexible, High Quality, Easy to Use Gas Detection System
Fully scalable, and designed to functional safety performance level 1 standards, the MX 43 is an analog and digital controller that continuously measures and controls gases in the atmosphere. The MX 43 gas detector manages both digital lines and analog channels, and covers all needs for a wide variety of gas monitoring applications. The MX 43 digital technology allows up to 32 detectors to be distributed on 8 lines for increased cost savings.
• Analog and digital controller
• 4 or 8 lines, up to 32 detectors
• Up to 32 fully programmable relays (OR, AND, NAND, NOR, Voting functions)
• Large graphic display
• Remote modules (cost savings on wiring installation)
• USB Data logging capability
• RS485 Modbus RTU and multiple analog outputs

USB Module for Improved Storage Capacity
Teledyne Gas and Flame Detection has improved the storage capacity of its MX 43 controller by adding an USB module. The USB option provides the user the following benefits:
• continuous data logging on the USB key at a user defined sampling rate from 2 seconds to 15 minutes,
• recording in real-time of all events (alarms, faults, alarm resets, calibration etc.)
• automatic backup of the configuration
• automatic backup of the firmware
• loading a configuration or a firmware file from the USB stick in order to restore or update the system easily.
The 4GB USB drive fitted with the USB kit, provides a recording capacity of more than 2 years (18 months in the worst case for a controller equipped with 32 detectors), a 2 second sampling rate (32 measurements every 2 seconds), and 100 events per day per gas detector (3200 events per day).
