Controller presentation The MX 4 is an analog and digital controller designed for the continuous measurement and control of the gases present in the atmosphere and for 4- ma or digital contact signal. Large graphic display Smart keys make embedded menus simple to use Front panel LEDs allow a quick and basic overview of the installation. MX 4 manages both digital lines and analog channels, and covers all needs for a wide variety of applications. The MX 4 digital technology allows up to detectors to be distributed on 8 lines for increased cost savings. 4 Internal battery Strobe and horn Power supply 4 6 on-board relays Removable terminals

GAS DETECTION CONTROL PANEL Modules Different modules can be connected to the controller: 4 or 8-relay module 4 or 8-programmablerelay module can be located closer to the actuators for cost savings. 6-logic-input module Addressable module of 6 logic input for recovery of digital information such as fire or intrusion alarms, emergency stop, limit switch activation, etc. 8-analog-input module Configuration example This module enables standard analog transmitters (gas or flame detectors for instance) to be connected on a digital line for cost savings. 4-analog-output module Addressable 4- analogoutput module which delivers 4 analog 4-mA 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.
