MK – 140 GAZ commutation module is a stand-alone device that meets oil and gas safety regulations. It’s operated with gas analyzer sensors. There are intrinsic safety barriers (a repeater RS-485), ex-marking [Ex ib Gb]IIA in MK-140.

According to GOST IEC 60079-14:2013 the device MK-140 with ex-marking is used in dangerously explosive areas and connected intrinsically safe circuit with electrical device in ex-rated ones.

 

Capabilities:

  • Intrinsically safe power supply sensors, digital transducers and other devices installed in ex-areas;
  • Status monitoring of connected devices;
  • Indication of current measurement channel readings on standard visual displays;
  • Settings threshold limit value for measurement channels;
  • Audible alarm activation when the thresholds are exceeded;
  • Quick audible alarm deactivation;
  • Warning lights activation when the thresholds are exceeded;
  • External actuator verification mode;
  • External safety actuator control;
  • Sending data to a DEL-150 control module for subsequent recording;
  • Indicating connection status to the DEL-150 control module.

Design Features:

  • Accessible connection with other devices if there are free outputs RS-485.
