LPI-400 Loop Powered Indicator – LED Display
The LPI-400 is a loop-powered indicator with a 4-digit LED display designed for process value indication in various industrial control and measurement applications such as pressure, flow, level, temperature, and humidity. It operates with a 4-20 mA loop current input from transmitters and offers a user-programmable interface with password protection, allowing for easy programming via push buttons. The indicator provides software calibration without the need for trim pots, reverse polarity protection, and a loop voltage drop of less than 5 VDC. It boasts a high accuracy of ±0.1% of full-scale value and features range locking/unlocking and offset adjustment capabilities. Users can choose between linear and square root operational modes, and the indicator has a fast display update rate. With a compact and robust enclosure, it is suitable for various environmental conditions.
