description The coil of an electric control device is energized by ac power controlled by a remotely generated logic level signal through a control module mounted in a cavity in the exterior of the device housing. The module contains a pair of back-to-back silicon controlled rectifiers (SCRs) mounted on a finned aluminum wall of the module which serves as a heat sink. An opto-coupler comprising a light emitting diode (LED) energized by the logic level signal and an opto-triac in series with resistors connected across the gates and cathodes of the back-to-back SCRs provides electrically isolated control of the conduction angles of the SCRs by the logic level signal.
