The PD686 is an FM Approved, CSA Certified intrinsically safe and non-incendive, 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 ½" 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.
