The MKS PDR900 Controller is a stand alone, single channel power supply and readout unit for use with all HPS® Series 900 digital vacuum transducers. The PDR900 features three high power setpoint relays for process control and a leak detection feature with an audible alarm.

The PDR900 can be used with both RS232 and RS485 transducers. It automatically detects the transducer type. It communicates digitally with the transducer, enabling remote control of transducer setup. The digital transmission of measurement data also eliminates analog measurement noise coupling via the transducer cables.

The controller can be used as a tool for configuration, calibration and diagnostics of system integrated transducers in OEM applications. RoHS and CE compliant, it offers user-selectable readout in mbar, Torr or Pascals and a built-in data logger for process monitoring and analysis. The PDR900 also features an easy to use, menu-driven user interface for simplified setup and configuration of transducer parameters. The controller's analog output and digital communication enhance the system's flexibility and ease of operation.
