Pin Description:VCC : Power Supply +GND : Power Supply -M+ : Motor +M- : Motor -GND : Trigger Signal -K1 : Forward input controlK2 : Reverse input controlS1 : Forward limit signalS2 : Reverse limit signal

Product Included:
1 x 30A Relay DC 12V 24V motor forward and reverse controller
Wiring Diagram 1: Two position (switch) reciprocating(moving backward and forward in a straight line.)
Wiring Diagram 2: Positive and negative start independently, each time running a single pass

Wiring Diagram 3: Every time you start, run a forward and reverse rotation

This module has 4 signal input terminals, namely ”K1”, ”K2”, ”S1”, ”S2”, K1 is the forward rotation signal input terminal, K2 is the reverse rotation signal input terminal, and S2 is the forward rotation limit signal Input terminal, S2 is the reverse limit signal input terminal. The signal input source can be selected from micro switch, induction, infrared, metal, remote control and other modules, and can also be controlled by a single-chip microcomputer.
