The PDR2000 is a low-cost two-channel power supply/display capable of supporting most 600-series Baratron capacitance manometers. It offers a very compact size （1/8 DIN package）, two （2） independently-adjustable relay trip points for external device operation, and selectable engineering units. It also can be ordered with an optional RS232C digital interface, and has the ability to scale to non-standard pressure ranges.
