The ATR243 controllerrepresents the top of the range and is the most versatile model of controllers in the 48x48 mm format (1/16 DIN) and is characterised by its high configurability which means it requires fewer product codes. The input can be programmed for temperature sensors, resistance thermometers and thermocouples, but also for pressure transmitters, humidity and flow sensors.
The controller's outputs can be selected as command/multiple alarm modes/analogue retransmission. The serial communication option is in RS485 with Modbus RTU/Slave protocol. Useful extended range power supply from 24 to 230V AC/DC with galvanic isolation from the network.
The functions of the ATR243 software include the PID hot-cold control algorithm, open-close logic for valve control, programming of a control cycle (up to 3 sections), maximum current threshold alarm.
