Model PD650

Large Display Universal Process Meter

The PD650 Large Display Universal Process Meter features 2.3" high digits housed in a rugged die cast aluminum NEMA 4X enclosure. The PD650 accepts the common process signals such as 4-20 mA, 0-5 VDC, and 0-10 VDC. It has all the features of the PD690 as well as a few new ones: dual 24 volt isolated power supplies for both the input and output loops and built-in relay suppression for more consistent relay operation. The PD650 can also function as a flow rate/totalizer, operating like our PD692. Features include: alternating rate/total display, programmable time base of second, minute or hour, automatic total reset, square root extraction, and many more.
