DIN rail PID  thermoregulator DRR227

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

DIN rail-mounted thermoregulator 43880 Single process setpoint, dual alarm threshold.

The analogue inputcan be configured for different types of temperature sensors RTD/Thermocouples and processes, the relay outputs and SSRs can be used as control and alarm.  An input is available for a TA current transformer with a maximum current threshold. Useful extended range power supply from 24 to 230V AC/DC with galvanic isolation from the network.

The software's functions include the SSR Burst-firing and Phase Angle control modes for inductive loads, resistive loads and infrared bulbs (monophase and triphase systems).

The digital input allows the 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 DRR227 thermoregulatorensures 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.
