Abstract
Abstract Apparatus for monitoring the operation of a wire-guided torpedo of the type having a number of control relays in the torpedo responsive to DC voltages from the control station. Each relay when actuated connects an AC source into the line, with a characteristic amplitude for each relay, providing an answer-back signal indicating proper operation of the relay. A voltage discriminating silicon controlled rectifier circuit in the control station responds to the answer-back signal lighting an indicator lamp to indicate which relay is actuated.
