Abstract
A shift register is provided with two inputs and two outputs. One input is from a free running clock and a second input is provided for relay operate and release signals. The two outputs are coupled to a NAND gate to provide a longer relay operate than release time. The two outputs are coupled to a NOR gate for a longer relay release time than operate time. Either gate output is coupled to a relay driver to operate the relay.
