Description
The Relay Control Assembly enables up to twentyfour (24) programmable relays to be added to the host control panel. The assembly includes a Relay Control Card (P/N 10-2778), Bus Card (P/N 10- 2769) and Interface cable (P/N 10-2784) as shown in Exhibit 1.
The bus card provides a mounting location for up to six (6) cards: CRM4 (P/N 10-2204) and/or HPM4 (P/N 10-2770). The relays can be used to provide system status indication, control of electrical loads, and general purpose switching. The bus card provides four green LEDs at each relay card position. The LEDs turn on to provide positive indication that the associated relay coil is energized.
