Precision Digital PD685 and PD686 3-1/2 Digit Loop-Powered Meters

These Precision Digital loop-powered indicators offer wide temperature range, low one-volt drop, and large 1"-tall digits that are easy to see at a distance. Calibration is a quick two-step process involving the adjustment of two non-interacting potentiometers. The only tools you need are a calibrated current source and a screwdriver.

PD685 is a low-cost, NEMA 4X indicator that can be installed in both indoor and outdoor general purpose applications. PD686 adds FM and CSA approvals for use in intrinsically safe and non-incendive installations.

The PD687 has been retired and is no longer available. Call for a suitable replacement unit.
