PID temperature controller DRR450

PID thermoregulator integrated into SSR module for multizone systems


  • <p>temperature regulators</p>

The DRR450 thermoregulator has been designed to control temperature and current on multizone systems via RS485 communication standard and Modbus RTU/Slave protocol.

It is extremely compact and features direct plug-in connection to the mono-phase SSR power module, reducing wiring costs and installation time.

The integrated current transformer allows monitoring of current on the load and management of the relative alarm.

In addition to SSR control output, a second output is available on the controller and it is programmable for alarms or heating/cooling PIDfunctions.

For monitoring and controlling systems up to 150 DRR450 units, Pixsys has developed the software SupervisorDRR450 running on PixsysPanel PC TD850/TD900.

Application fields include plastic extrusion, injection moulding, packaging, furnaces, dryers, textile machineries and generally multizone heat treatment systems.

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.

Programming of  PID  controllerDRR450is supported by LABSOFTVIEW software.

Our youtube channel features video tutorials for initial set-up of SupervisorDRR450.

As for the entire range of PIXSYS products, traceability of the product is guaranteed during its entire life cycle by QR code; information and documentation online can be accessed reading QR CODE by mobile device with immediate visualization of technical data and check of warranty status.
