The PD686 is an Intrinsically Safe and Nonincendive, NEMA 4X, loop-powered indicator that is easy to install and program and can be seen from considerable distance. 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 the PD685's 1 V drop results in a minimal burden on the loop. The meter features FM and CSA approvals as Intrinsically Safe and Nonincendive, a wide -40 to 85°C operating temperature range, and is provided 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 two non-interacting potentiometers.
