Modules

MU-140 Control Module

The control module consists of the following functional parts:

  • a digital board with a processor, including digital and scale display circuits, a keyboard, a communication channel based on serial interface 485, an alarm circuit, an automatic indicator bright control circuit;
  • a supply board generating voltage to power devices of the DEL-140, including safety devices, electronic security circuits, power filters, a static power supply unit providing galvanic isolation from input circuits,
  • a blocking unit, including electronic keys for audio alarm and control of an air valve locking-up a hoist brake;
  • a demountable memory unit recording controlled technological parameters;
  • a DataFlash system (a so-called "black box");
  • a data communications unit (optional).

MK-140 Switching Module

The switching module is a rectangular cross-section body which contains:

  • sockets to connect communication and current supply cables of devices of the DEL-140 electronic dynamometer;
  • a supply board generating voltage to supply devices in an explosion hazard zone and including safety devices, electronic security circuits, power supply filters, a static power supply unit providing galvanic isolation from input circuits, spark-protecting units in outputs of each particular current supply line with the "Spark-safe electric circuit" type of explosion protection;
  • spark-protecting units are thermosetting compound-filled to ensure intrinsic safety;
  • cable inlets on a lower bar of the body.

MK-140 is installed next to the MU-140 control module outside an explosion hazard zone to ensure intrinsically safe power supply of devices placed in an explosion hazard sone.
