Self-locking (bistable) reverse polarity controller Input voltage: DC 5V (5V version) / DC 6-24V (12V version) Module working current: 2mA forward rotation, 35-40mA reverse rotation Load voltage: equal to output voltage Load current: maximum 2A (motor load maximum 1A) Equipped with power indicator and reverse polarity indicator Control mode: low pulse control This is a self-locking (bistable) reverse polarity relay. One trigger produces reverse polarity output (and holds state); second trigger returns output to normal (input equals output, and holds state). Pinout: I+: Power input + I-: Voltage input - O+: Power output + (outputs - when polarity is reversed) O-: Power output - (outputs + when polarity is reversed) G: Trigger signal ground T: Trigger signal input (0.2–2 second low pulse) Operation instructions: After power-on, output equals input. Press the trigger button to activate reverse polarity output. Press again to return output to normal (input = output). Third press restores reverse polarity output. Sequence continues ingly. Power off stops all output. Dimensions: 43mm x 21mm x 16mm Material: PCB Color: Green Package includes: 1 x Reverse polarity controller Note: Light reflection and display differences may cause slight color variation between image and actual item. Measurement error allowed within +/- 1-3cm.
