The 1 Pole Relay Board mounts directly in Apprentice II lighting control panels and is designed to control up to 347 VAC loads. This one pole relay assembly mounts directly in place of the SoftCross single pole relay board. The relays are electrically held, are available in N.O. (normally open) contacts, and can be mixed in the lighting controller with SoftCross relay boards. These relay boards are easily mounted in the Apprentice II panel with a push-on connector interface and a single screw.
