OR
OperationInput to A or B will produce output at C.
Expressing outputLow electrical potential (L) at A and B → no output (L) at C. High electrical potential (H) at A or B → output (H) at C.
Simple relay circuitsOR relay circuit
AND
OperationInput to A and B will produce output at C.
Expressing outputHigh electrical potential (H) at A and B → output (H) at C. Low electrical potential (L) at A or B → no output (L) at C.
Simple relay circuitsAND relay circuit
INV
OperationNo input to A will produce an output at B. An input to A will not produce an output at B.
Expressing outputLow electrical potential (L) at A → no ground (H) B. High electrical potential (H) at A → grounds (L) B.
Simple relay circuitsINV relay circuit
PROCESS
OperationSimplified representation of complex functions within circuit; describes main function. 1. Signal detector for engine control unit, cooling unit, and tachometer. 2. Signal converter for turn and hazard flasher unit and igniter unit.
Expressing output
Simple relay circuits(Examples) Igniters; Signal converter: Coil signal converted to ON/OFF signal
