Technical data

The HESCH multifunction controller is designed for universal installation in 1/4 DIN format. Via the 3.5″ touch screen and the four freely programmable keys, the usage is very user-friendly. The basic device offers slots for two I/O cards and a communication card, which can be selected individually depending on the application.

I/O cards

I/O card type 1:

  • two galvanically separated analogue universal inputs (for measuring temperatures, voltages, currents, resistances, norm signals, etc.)
  • two galvanically separated standard signal inputs (current/voltage)
  • two galvanically separated analogue outputs (current/voltage)
  • six digital inputs/outputs (user-programmable as input or output)

Further I/O cards on request.

Communication cards:

The HESCH multifunction controller offers the following communication cards:

  • Profinet
  • Profibus
  • Modbus RTU Master
  • Modbus RTU Slave
  • Modbus TCP Client
  • Modbus TCP Server
  • CAN Bus
  • HPR Bus Master

Further communication profiles on request.

Relay outputs:

The HESCH multifunction controller offers four potential-free relay outputs with change-over contacts.
