A small panel meter is useless if nobody can read it from the walkway. The Precision Digital PD4-6604 Loop Leader+ puts a 4-20 mA process value on large 2.8″ (71 mm) characters, with units, a tag or a message on a 1.5″ (39 mm) second line and a 20-segment bargraph with percent.
It is powered entirely by the loop with a maximum drop of 2.1 V, so it can be added to an existing transmitter loop without new power wiring. The large 2.8″ (71 mm) top line and 1.5″ (39 mm) bottom line are easy to read from a distance, and the backlit display flashes red on alarm.
The NEMA 4X, IP65 enclosure mounts on a wall or pipe. Two open collector outputs are standard, with options for loop-powered solid-state relays and an isolated 4-20 mA output.
