This compact PID controller features high configurability. The analogue input is programmable for temperature sensors (resistance thermometers, thermocouples) but also for pressure transmitters, humidity and flow sensors.
The heating-cooling PID control algorithm is optimized for both temperature regulation and for processes with quick transitory, like pressure and flow control.
Software features of the ATR121 include open-close logics for valve control in industrial HVAC and dosing systems.
The controller outputs are always freely selectable selectable as command/multiple alarm modes/events.
