Relay Interface Module II
EATON Powerware
An optional Relay Interface Module II (RIM II) uses relay contact closures to indicate
the operating status and alarm condition of the UPS system. The module uses a serial
interface line and may support up to eight critical loads. The RIM II can be
flush-mounted or surface-mounted on a desktop, or secured to a wall. Figure 8-4
shows the RIM II with its four 15-pin connectors labeled J1 through J4.
