Current Loop Display

LPD

Simple Scalable Display for Analog Signals

Local display designed to be inserted into a 4-20 mA sensor current loop.

Description

Loop Powered
The LPD is all about loop-powered circuits, perfect for installing just outside hazardous locations and displaying the readings from your intrinsic safety devices. The LPD has a 4-20 mA input and output.

Simplified User Interface
With just three buttons, and a large, two-line LCD display, using the LPD is straightforward and uncomplicated.

Optional Modbus RTU Programming
Alternatively, you can connect to the LPD from a PC running APG Modbus software via an RST programming module for quick and easy setup.
