"  2 or 4 Relays + 4-20 mA Output Options "  115 or 230 VAC field selectable power "  Rate display in units per day, in addition to second, minute and hour "  Programmable set points for latching and non-latching relay operation "  Built-in snubbers on each relay contact "  Any set point programmable for process/rate or total "  Programmable root function for Weirs and Flumes "  Pump Alternation DETAILS The PD656 is a Large Display Process Meters 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 0.8" high 4-1/2 digit red LED display. The PD656 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 PD656 is housed in an explosion-proof sand-cast aluminum enclosure. An optional magnetic key is available to operate and program the meter without having to remove the enclosure cover. The PD656 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.
