<p>MULTI-MODE CONTROL LOGIC CIRCUIT FOR SOLID STATE RELAYS For providing an interface between a low level input control signal and a power switch, a control logic circuit is presented for permitting operation of a solid state relay in any one of a plurality of modes of operation including operation as either a normally open relay, a normally closed relay, or a latching relay, and also to make possible combinations of such relays for operation in parallel with a second relay operating in or out of phase with a first relay. The control logic circuit includes logic gates with means for selective interconnection of external terminals to set the operation in the desired mode as well as to permit one relay to be responsive to the condition of another.</p> |
