DRR244 | DIN Rail PID Controller

PID Controller DRR244 stands out in the DIN-rail controller segment thanks to its comprehensive hardware and software features resulting in a single order code.

The analog input is programmable for temperature sensors such as resistance thermometers and thermocouples, or for current/voltage process signals frequently used by pressure transmitters, humidity and flow sensors or inverters.

The outputs are selectable as command , multiple alarm modes or analogue retransmission.

For applications within networks the serial port is RS485 with Modbus RTU/ Slave protocol.

The extended range power supply from 24 to 230V AC/DC with galvanic isolation makes it suitable even in case of oscillation in the power grid.

In addition to its function as a hot-cold PID controller, DRR244 also finds application as a signal converter due to the availability of analog output galvanically isolated from the input, which can be used for retransmission of process value or setpoint .

Like the other models in the Blue Line series, DRR244 is programmable with MyPixsys App via NFC/RFID communication.
