Feature:1. This is a self-locking (bistable) reverse polarity relay. Trigger once, output reverse polarity (and hold), trigger again, output = input (and hold).2. Self-locking (bistable) reverse polarity controller, the module can just control forward and reverse (start and stop are controlled by power on and power off).3. With power indicator and reverse polarity indicator.4. Low pulse control mode, more convenient to use.5. Made of high-quality electronic components, stable and reliable performanceSpecification:Item Type: CW/CCW Controller ModuleOptional Input voltage: DC 5V (5V version), DC 6-24V (12V version)Module working current: forward 2MA, reverse 35-40MALoad voltage: equal to output voltageLoad current: maximum. 2A (motor <= 1A)With power indicator and reverse polarity indicatorControl mode: low pulse controlSize: Approx. 43 x 21 x 16mm / 1.7 x 0.8 x 0.6inWeight: 13.5 g / 0.5 oz(approx.)Pin description:I +: power input +;I-: voltage input-;O +: power output + (The output in reverse polarity is-);O-: power output-(The output in reverse polarity is +);G: trigger signal ground;T: trigger signal input (0.2-2 seconds low pulse).Instructions:1 After power on, output = input, press the trigger button, reverse polarity output, trigger the button again, output = input, third trigger button, reverse polarity output. And so on.2 Turn off the power and stop the output..Package List:1 x CW/CCW Controller ModuleNote:1. For the module to work stably, be sure to use a power supply that is twice the load power. If the load is a motor, use a power source with more than 3 times the power.2. The maximum load current is 2A. If it is a load motor, the maximum load current is 1A.3. The module can only control forward and reverse (start and stop are controlled by power on and power off)
