Description
MX 52 controller accepts inputs from flammable (4-20 mA transmitter or catalytic bridge types) and toxic gas detectors. The MX 52 modular design allows you to build your own gas detection system to meet your requirements.

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
