digital temperature regulator / programmable / PID / process
Max.: 45 °C (113 °F)
Min.: 0 °C (32 °F)
This 32x74 controller is highly configurable, which means it requires a lower number of product codes. 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 process variables with quick transitory, like pressure control and flow control.
The software functions of the ATR121 include the open-close logic for valve control on industrial thermoregulation, air conditioning, dosing systems.
The controller's outputs can be selected as command/multiple alarm modes/event. The serial communication option is RS485 with Modbus/Slave protocol.
