Pixsys ATR121-B Controller

The Pixsys  ATR121-B series of digital controllers are highly configurable. The inputs 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-B 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.
