This controller 32x74 with dual 4-digits display is characterised by high configurability of the input and by a multi-voltage power supply from 24 to 230V AC/DC galvanically isolated and that does not require hardware selections. This translates into a single product code, which is one of the most versatile controllers in the 32x74 format. The input can be programmed for temperature sensors, resistance thermometers and thermocouples, but also for pressure transmitters, humidity and flow sensors. The algorithm for heating-cooling PID control is optimised both for temperature control and for processes with quick transitory, like pressure control and flow control.
Functions of the ATR142 software also include Timer, with the options of delayed start of the control process or time-based control.
The outputs can be selected as command/multiple alarm modes/event. The serial communication option is RS485 with Modbus/Slave protocol.
