MX52 16 Channel Alarm/Display Unit

MX52 16 Channel Alarm/Display Unit

2-3 Weeks Del.

Quick Overview

MX52 is a modular control panel for up to 16 channels. The MX52 connects to the OLC, CEX and CTX ranges of gas detectors, plus any other 4-20 mA device can be monitored and controlled. The unit is an alarm/display unit with fixed or scrolling display, 3 programmable alarm thresholds per channel, fault alarm, analogue and serial outputs.

Features
  • Programmable keyboard
  • Modular control panel (3U, 19")
  • Master digital display
  • Up to 16 channels
  • 33 gas alarm thresholds, one with time delay, 1 common fault alarm
The innovative features of the MX 52 are integrated into a 3U 19” rack frame for use in a variety of applications. The MX 52 can be programmed either through the keyboard or by an external PC.

Each of the 16 channels performs the following:

  • continuous monitoring of connected detector(s)
  • cyclic display of the detected gas, its status, content and unit (ppm, LEL or %)
  • alarms are initiated if concentration exceeds preset thresholds
  • relays activated to enable external warning devices (valves, audio/visual alarms)
  • fault alarms
  • 4-20 mA outputs
  • serial RS485 Modbus interface
