This module can be used to control polarity on output, for ex. to control DC motor rotation direction. Can be operated through a microcontroller, as well. Input voltage: DC 5V Module operating current: forward 2mA, reverse 35-40mA Load voltage: equal to the input voltage Load current: maximum. 2A (motor less than 1A) With power indicator and reverse polarity indicator Control mode: button-operated Dimensions: approx. 43x21x16 mm Pin Description: I+: power input +; I-: power input-; O+: power output + (reverse polarity output -); O-: power output- (reverse polarity output +); G: Trigger signal ground; T: trigger signal input (low pulse 0.2-2 seconds). How to use: 1. Power on, output = input, press the button, reverse polarity output, press again, output = input, third press, reverse polarity output, etc. 2. Turn off the power and stop the output https://elecena.pl/product/22626332/dr55b01-bistable-self-locking-reverse-polarity-relay-module-dc5v-motor-forward-reverse-controller 2023-02-23 https://elecena.pl/product/22626332/dr55b01-bistable-self-locking-reverse-polarity-relay-module-dc5v-motor-forward-reverse-controller 2025-10-28
