PID Temperature Controller 48x48 mm ATR227

Control and alarm functions, optional Burst-firing and Phase Angle control, multi-voltage power  supply 

Temperature controller 48x48mm (1/16 DIN), Single process setpoint value, double alarm threshold (example: maximum temperature threshold and minimum temperature threshold).

Input is programmable for different types of temperature sensor RTD/Thermocouple and process, Relay and SSR outputs are available. It features also the extended range power supply 24 to 230V AC/DC with galvanic isolation.

The software functions include SSR Burst-firing and Phase Angle control for monophase inductive and resistive loads or infrared lamps (code -12ABC).

The digital input allows external activation of various functions, including selection of automatic/manual mode.


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 ATR227 thermoregulator ensures 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.
