  • Start-up pulse suppression circuit for industrial controller output
    Patent number: 5243232
    Abstract: A flash-on reduction circuit for use in the binary state output circuitry of an industrial controller employs a current conductor to charge parasitic capacitances of the output circuitry when the industrial controller is first turned on and a current limiter for preventing high current flows through the output power stages of the output circuit when the industrial controller is first turned on. The current limiter is deactivated by a timing means after the parasitic capacitances have been charged by the current conductor. In a first embodiment, the current conductor and current limiting means are provided by a current source applying increasing power to the output circuit.
