The ATR244 is a 1/16th DIN PID controller that has all of the features you need for even the most demanding process control applications. It has a high-performance display which ensures excellent readability and can be programmed with NFC/RFID technology via our App without the need for wiring and device power supply. It accepts most process sensors allowing it to work in temperature, pressure, flow and just about any other control application.

Universal Input
The ATR244 can accept inputs from most temperature and process sensors. The ATR244-12ABC has a single analog input and ATR244-23BC-T has two analog inputs. The inputs can be configured for the following signal types:

• Thermocouples: K, S, R, J, T, N, E, B
• RTDs: PT100, PT500, PT1000, Ni100,
• Thermistor: PTC1K, NTC10K ( 3435K)
• Process Signals: 0-1Vdc, 0-5Vdc, 0-10 Vdc, 0/4-20mA, 0-60 mVdc
• Potentiometer: 1-150 K

Models with Single or Dual Input
The ATR244-12ABC has a single analog input and ATR244-23BC-T has two analog inputs. The dual input model can manage two processes with two separate control loops or the two inputs can be used to perform mathematical operations between the two processes (sum, difference, average).

Multiple Outputs
The ATR244 is offered in two models and both models offer relays, pulse outputs for SSRs and analog outputs.

Autotune or Manual Tune
All PID controllers need to be tuned to a process for optimal control. The ATR244 can be set to automatic tuning which allows the controller to perform the tuning function or it can be set to manual tune for those users who want full control over the tuning process.

Auto-Adaptive PID Control
The PID control parameters can be tuned either automatically or in an auto-ad
