MKS Instruments PDR-C-1C Power Supply Readout Pressure

Description

MKS Instruments PDR-C-1C Power Supply Readout Pressure. Condition is "Used".
Standard Half-Rack Mount Unit
Provides ±15 VDC at up to 600 mA
(2) Single Pole Relays
4½ Place Digital Panel Meter
The MKS Type PDR-C-1C and PDR-C-2C are power supply and digital readouts which are packaged in standard half-rack mount units. The PDR-C-2C is designed to provide power for, and accept the outputs from two pressure sensors. The PDR-C-1C is identical to the -2C except the -1C is designed for operation with one pressure sensor.
The power supply for both the -1C and -2C is capable of providing ±15 VDC at up to 600 mA. This will provide enough power for two MKS Baratrons or for any electronic manometer with similar input requirements.
The unit contains two set point-operated, single pole relays which may be controlled by either pressure channel in the -2C. Set point adjustment is accomplished by front panel COARSE and FINE controls which cover the entire range of the gauge in use. The relays status is indicated by front panel lamps. Failsafe relay operation is standard, that is, the relays are not energized at pressures higher than the set point settings. The relays can be latched in the energized state by means of an external logic line to the rear panel Interface connector.
The readout is a 4½ place digital panel meter which indicates the output of the attached pressure sensor(s). Engineering units for the readout can be selected by a front panel switch. The meter also reads the current set point values in the same engineering units by means of another front panel switch. The PDR-C-2C has an additional front panel switch which is used to select display of channel 1, display of channel 2, remote channel selection, or automatic channel selection. In automatic channel selection, the PDR-C-2C will display Channel 1 sensor as long as it is less than 100%. If Channel 1 is greater than 100%, Channel 2 will be displayed.
