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 4-20mA 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.
