MK-140 (M4) is an extension for the DEL-150 configuration and it’s made to meet the customer’s technical needs.

MK-140 (M4) is the best option to connect 1-3 devices. 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 to the sensors and other devices from SKPB DEL-150;
  • Connecting a control module to extra devices (sensors, remote indicators, transducers, actuators);
  • Commutation modules can be connected in series.

Design features:

  • Two modifications for power supply connection.
