NE872A Distribution Monitor and Control Module
Overview
The NE872A (CC109124780) allows the Pulsar Plus family of controllers to manage various distributions
through serial communications in rectifier and converter based systems. The system controller will
communicate over the GP RS485 bus to the NE872A and monitor associated alarms for open load or battery
protectors, measure a single shunt configured as a load or battery shunt, monitor the DC bus voltage for
back-up LVD functionality, and control and monitor a single load or battery latching LVD contactor. The
board allows addressing for up to eight NE872As being installed in a system. Figure 17 shows the
connections and interfaces for the NE872A.
