PD655 1.0" Display Plastic NEMA 4X Meter
PD655 1.0" Display Plastic NEMA 4X Meter
PD655 1.0″ Display Plastic NEMA 4X Meter
GENERAL FEATURES
The PD650, PD655 and PD656 are Large Display Process Meters with flow rate, totalizer and batch control capabilities. Each 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 large, high efficiency, 4½digit red LED display. All units also provide two isolated 24 V power supplies to drive both the input and output loops. Options include up to 4 relays for alarms or batch controlling, as well as an isolated 4-20 mA transmitter output.
Single Button Scaling
Single button scaling means that these meters can be completely programmed using only one button. Simply press the ENTER button to initiate the automatic menu scan. When the desired menu appears press the ENTER button again. Once in a menu, press the ENTER button when the display reads the desired value. To exit setup & programming press the ACK (Acknowledge) button while displaying any of the main menus. It’s that simple!
