Description
APG LPD Series Loop-Powered Displays are designed to be inserted into a 4-20 mA sensor current loop to provide a local display without additional wiring. Setup is easy using the 3 buttons on the display. Simple scalable display for analog signals. Local display designed to be inserted into a 4-20 mA sensor current loop.
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.
