The ILC Softcross relay is designed for the Apprentice II lighting control panels. This relay features true zero cross switching that eliminates arcing on the contacts, thus enhancing relay endurance and reliability. The relay board´s circuitry is designed to prolong its life to an average of 10,000,000 cycles. Softcross relays are electrically held and are available in NO (normally open) and NC (normally closed) types, and relay types can be mixed in the lighting controller. Softcross relays are mounted in the panel with a push-on connector interface and a single screw.
