PD686 Loop-Powered NEMA 4X Intrinsically Safe & Nonincendive Digital Meter

Brand: Precision Digital Corporation

The PD686 is an FM Approved, CSA Certified intrinsically safe and nonincendive, NEMA 4X, IP67 loop-powered indicator that is easy to install and program.

It can be seen from considerable distance and even in bright sunlight.

The fact that this meter is loop-powered means that there is no need to run additional, costly power lines into a hazardous area.

The meter gets all of the power it needs from the 4-20 mA loop and its 1 V drop results in a minimal burden on the loop.

The meter features a wide -40 to +85°C operating temperature range and is available with a 1/2" conduit hole in a location of your choice for easy installation.

Calibration is a quick two-step process involving the adjustment of only high and low, non-interacting potentiometers.
