ATR121 | 32x74 mm PID Controller

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.
