Another handy building block circuit. Two independent relays, both controlled by relay-driver transistor logic. Each relay can be used with an active-high signal or active-low (TTL switching levels). Relay contacts are rated to switch 250VAC at 12A (high current operation requires high-current wiring to supplement the PC board traces). Requires +12Vdc supply (not included).
