Controllers with RS232/485 interface

Controllers with a serial interface can be controlled centrally by a PLC. JUMO controllers communicate with other systems via the RS232/485 interface and protocols such as Modbus TCP or Modbus RTU. Some controllers can also take over control themselves thanks to the Modbus master.
