Automation Products Group Inc. (APG) introduces a new display product, the "LPD" or Loop-Powered Display, ideal for installations that use loop-powered wiring. The LPD displays are designed to be inserted into a 4-20 mA loop-powered sensor system to provide a local display without additional wiring. Setup is easy using just three buttons on the display. It can be used in places where explosive gases might be present such as oil fields, chemical yards, refineries, wastewater treatment plants or pumping stations. A secondary purpose is to convert analog signals to a digital Modbus signal for incorporating with modern communication protocols.
