Gas Detection Control Panel MX Analog and digital controller or 8 lines / 6 to s max Highly versatile controller SIL reliability Fixed The Fixed Gas Gas Detection Detection Experts People www.oldhamgas.com
Controller presentation The MX is an analog and digital controller designed for the continuous measurement and control of the gases present in the atmosphere and for - 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 manages both digital lines and analog channels, and covers all needs for a wide variety of applications. The MX digital technology allows up to s to be distributed on 8 lines for increased cost savings. 6 Back-up battery Strobe and horn Power supply On-board relays Removable terminals 6 RS8 output USB datalogging kit

GAS DETECTION CONTROL PANEL Modules Different modules can be connected to the controller: or 8-relay module 6-logic-input module or 8-programmablerelay module can be located closer to the actuators for cost savings. 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 -analog-output module Configuration example This module enables standard analog transmitters (gas or flame s for instance) to be connected on a digital line for cost savings. Addressable - analogoutput module which delivers analog -ma signal outputs ( output copy, min, max, average of a group of s) for connection to a datalogger, a PLC, a Building Management System (BMS), etc.
