摘要： A solid state unipole relay, preferably for use in a modular system for providing solid state power control, comprising two discrete elements employable in different combinations to form a multipole relay with convertible contact functions and including a circuit which supplies two discrete output terminals with a train of pulses to enable gating of a Triac or Triacs associated with that particular output terminal, and wherein the operation of the circuit is such that during normal operation a train of pulses is applied to one output terminal which is connected, in turn, to an associated gate circuit of one or more Triacs but when a control signal is applied to an appropriate point within the circuit the first train of pulses is inhibited and a second train of pulses, fed to a second output terminal, is actuated to control the associated gate circuit of one or more Triacs that are independent of the first mentioned Triac or Triacs.
