The PDR2000A is a versatile, low cost solution for powering and displaying up to two (2) Baratron® transducers. Both instruments are simultaneously powered, so users may alternate between readings with the press of a button. Readings are also available on demand via the RS-232 interface.
Two process relay trip points are available and may be assigned to either of the two manometer channels. Upper and lower settings allow the user complete control over the hysteresis of the control trip point. The relays have isolated outputs and are rated for 2 Amps at 240 VAC.
The PDR2000 provides ±15 VDC, 750 mA to power a capacitance manometer and displays the 0 to 10 VDC pressure transducer output in Torr or mbar Units. A 9-pin type "D" connector is used to interface the Baratron® manometers.
