Temperature controller V24 ATR121 AD

The temperature controller ATR121 convinces by its compact design and the versatile application possibilities. With our temperature controller you can reliably control and monitor your temperature readings. Alternatively, you can also use the controller as a temperature display. Our temperature controllers are very flexible: You can not only connect all common resistance-based temperature probes (PT, Ni and NTC) or thermocouples to the input. You also have the option of integrating other measured variables such as humidity or pressure at the input of the temperature controller via a standardized analog signal (0/4...20 mA / 0...10 V). Transmitters can be supplied with auxiliary power directly via the temperature controller. Potentiometers can also be connected.
As with the possible input signals, our temperature controller is also characterized by its diversity and flexibility with regard to the output signals. Two full-fledged relays (1 x NO/NC and 1 x NC), as well as a digital HL relay for the logic level output are available.
Our temperature controller makes configuration easy for you - it features a PID controller and a practical self-optimization function. Thanks to extensive programming options directly via the display or with the help of the free software, alarm values can be set easily and accurately. You can conveniently store all configuration parameters on a memory card and thus also copy them to other controllers. You have the choice of several alarm functions and can ideally set switching thresholds thanks to the adjustable hysteresis.
