289H LSS Card Components
Dedicated Relay Card (P/N 9800-6110)
There are three types of relay cards available for the 289H LSS: subscriber, dedicated and Sparton Dedicated Replacement (SPDR). The Dedicated Relay Card (shown on the right) is equipped with 50 relays to provide monitoring of resistive output devoces and current loop output monitoring devices on dedicated conductor pairs.
Dedicated Relay Cards currently being supplied by System Studies are equipped with the on-board capacitors and circuitry required for full tone generation capability–both the "pair-saver" and "locator" tone functions.
