Introduction
The HLI is compatible with any device that provides a 4-20mA output and does not need a separate power supply. The most common use for the HLI is providing an easily accessible field display that indicates the measurement of a loop powered device. The user may place it anywhere in the wiring run of the loop so there is no need to walk a long distance or climb a tall vessel to view an instruments display. Some instruments do not include a display at all, so the HLI can add this feature to the users installation.
