The PD685 is an ATEX and IECEx intrinsically safe, IP67 loop-powered indicator that is easy to install and program. It can be seen from considerable distance in bright sun or dimly lit areas when the standard backlight feature is activated. 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 (4 V with backlight) drop results in a minimal burden on the loop. The meter features a wide -40°C to +75°C operating temperature range and is available with a 22 mm (0.865″) conduit hole in a location of your choice for easy installation. Calibration is a quick two-step process involving the adjustment of only two sets of coarse and fine, non-interacting potentiometers.
