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

Brand: Precision Digital Corporation
Request Information
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.
Features
  • NEMA 4X, IP67 Loop-Powered Field-Mount Process Meter
