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.
