APG Introduces LPD  Loop-Powered Display

April 15, 2015 - Automation Products Group introduced LPD 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.

The LPD provides a display that 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. In this way, it fits into APG’s Tank Cloud remote monitoring system, which works off of Modbus. This is another way to convert an analog signal to a digital one to be sent over the Internet for reading on a browser.

This display has the ability to connect up to ten (10) 4-20 mA sensors to any of Tank Cloud’s Modbus masters, including the MND display, by converting to Modbus. One master could connect to 10 LPDs, with one analog sensor connected to each.
