Pump Alternation
The PD655 is a Large Display Process Meter with flow rate, totalizer batch control and pump (with alternation) control capabilities. It accepts the common process signals such as 4-20 mA, 0-5 VDC, 1-5 VDC and 0-10 VDC and displays these signals in engineering units on a 1" high 4-1/2 digit red LED display. The PD655 can also provide two isolated 24V power supplies to drive both the input and output loops. Options include up to 4 relays for alarms, pump control or batch control, as well as an isolated 4-20 mA transmitter output. The PD655 is housed in a rugged polycarbonate, NEMA 4X enclosure. The PD655 can be modified to provide up to 100 mA to drive mass flowmeters, ultrasonic level transmitters and other devices that require more than 20 mA to drive them.
