The Elk 12 Volt Relay Module is a high quality DC relay with SPDT (Form "C") dry contacts. It features low current draw, positive or negative activation. In the case of a BDA or BBU, these devices will control the relay coil circuit when an event occurs, i.e.- an alarm, thus toggling the respected relay contacts. Dry contacts have a power source going through them that is independent of the control circuit. It's like a contactor or relay.
