The PD650 is a 2.3 in. high LED display universal process meter, housed in a heavy-duty, die-cast aluminum NEMA 4X enclosure. The PD6555 is a 1.0 in. high LED display universal process meter housed in a rugged, impact-resistant, glass-filled polycarbonate NEMA 4X enclosure. The PD656 is a 0.8 in. high LED display universal process meter housed in an explosion-proof NEMA 4 sand-cast aluminum enclosure.
With 4½ digits plus an extra zero for process/rate and full six digit for total, all three meters accept common process signals including 4-20 mA, 0-5 and 0-10 VDC. Additionally, all three have two 24 VDC isolated power supplies to power the input and output loop; and each can function as a flow rate/totalizer. Features include pump alternation function, alternating rate/total display, automatic total reset, external lockout capability and programmable root extraction for weirs and flumes. Field switchable 115/230 VAC is standard and options include 2 or 4 relays with built-in relay suppression for more consistent relay operation and isolated 4-20 mA output.
