This is a self-locking (bistable) reverse polarity relay. Trigger once, output reverse polarity (and keep), and trigger again, output=input(and keep)
Pin description:
power input +;
I-: Voltage input -;
O+: power output + (when the polarity is reversed, the output is -);
O-: power output-(the output is + when the polarity is reversed);
G: trigger signal ground;
T: Trigger signal input (0.2-2 second low pulse).
Instructions:
1 After power on, output = input, press the trigger button, reverse polarity output, trigger the button again, output = input, trigger the button for the third time, reverse polarity output. And so on.
2 Turn off the power and stop the output.
Note:
1.Due to the light and screen difference, the item's color may be slightly different from the pictures.
2.Please allow 1-3cm differences due to manual measurement.
3.In order for the module to work stably, be sure to use a power supply that is more than twice the load power. If the load is a motor, please use a power supply with more than 3 times the power.
4.The maximum load current is 2A, if it is a load motor, the maximum load current is 1A
5.The module can only control forward and reverse rotation (start and stop are controlled by power-on and power-off)
