PID controller DRR244 stands out in the segment of rail-mounted controllers thanks to its flexibility and configurability that are summed up in a single ordering code. The analogue input can be programmed for extensive range of temperature sensors (resistance thermometers and thermocouples) as well as for process signals mA/Volt (typically pressure transmitters, humidity and flow sensors). The outputs can be selected as command/multiple alarm modes/analogue retransmission. Serial communication is RS485 with Modbus RTU/Slave protocol. The controller is equipped with extended range power supply 24 to 230V AC/DC with galvanic isolation from the network.
