Using efficient mechanical relays, the BCC40R provides contact-closure on/off control of eight AC-or DC-powered devices for data acquisition and control applications. The relays are controlled by writing to a board-specific I/O address and can be controlled either as a set of eight relays at a single I/O address or individual relays at eight separate I/O addresses. Four of the relays have single-pole, double-throw (SPDT) output connections and four relays have single-pole, single-throw (SPST) output connections.
