Configurable PID controller 72 x 72 mm ATR171

Control and alarm functions, timer, digital input, multi-voltage power supply, analogue retransmission options and double programmable input


  • <p>Temperature controller atr171 multi setpoint </p>

PID controller 72x72mm, with dual 4-digits display for high visibility in the industrial environment, distinguished by high configurability.

Two inputs can be programmed for a wide range of sensors. The outputs can be set as control, alarm, or analogue retransmission. The serial communication option is RS485 with Modbus RTU/Slave protocol. Power supply range from 24 to 230V AC/DC with galvanic isolation from network and galvanic isolation between inputs and analogue output.

The heating-cooling PID control algorithm can also be used for cascade control through remote setpoint by analogue input.

The digital input allows external activation of various functions, including the Timer for delayed start or timed control.


User friendly, multimedia support and traceability

For the entire range of Pixsys products we provide technical support for installation, programming and operation via our online forum and via Skype.

The interface of the PID controller ATR171ensures that the product is easy to use and that the user is also supported by auxiliaries for programming such as MEMORY-CARD or the LABSOFTVIEW programming software

Programming tutorial videos are available on our youtube channel.

As for the entire range of PIXSYS products, thanks to the QR code the traceability of the product is guaranteed for its entire life cycle; the information and documentation online can be also be accessed by reading the QR CODE that directs your mobile device to the product's technical specifications and verifies its warranty conditions.
