DR55B01 Bistable Self-Locking Reverse Polarity Relay Module - DC5V - Motor Forward/Reverse Controller

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
