PD650 Aluminum NEMA 4X Process Meter With 2.3" Display
Manufacturer: Precision DigitalThe PD650 is a large display, analog input process meter with flow rate/totalizer and batch control capabilities housed in a rugged, die-cast aluminum, NEMA 4X enclosure.
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 2.3" (58.42 mm) large, high efficiency, 4-1/2 digit LED display.
The 115/230 VAC models also provide two isolated 24 V power supplies to drive both the input and output loops.
Options include up to 4 relays for alarm or batch control and an isolated 4-20 mA transmitter output.
