eletechsup DC 5-24V 3-5A Flip-Flop Latch DPDT Relay Module Bistable Self-Locking Double Switch Board for Arduino UNO MEGA AVR LED -DC 5V- 1-

Description:    3A Flip-Flop Latch Self-locking (bistable) DPDT Relay controller 1 Input Voltage: DC 5V(5V version); DC 6-24V(12V version) 2 Module working current:Standby 1-2ma;Relay is on: 60-71MA; 3 Load current: Maximum 5A(Motor <=3A) 4 Power indicator AND Working indicator 5 Control method : low pulse trigger 6 Size: 39.5mm X 33.3mm X 23.3mm 7 Weight: 23 g This is a bistable (self-locking) relay module,Trigger once, the relay pull (and holds);Trigger again, the relay releases (and holds) Module interface: 1. V  positive power supply (VCC) 2. G negative power supply (GND) 3. T  : Low pulse trigger(0.2-2 second low pulse trigger)      DPDT Relay outputs: 1. NO1: normally open relay interface 2. COM1: Common Interface Relays 3. NC1: normally closed relay interface 4. NO2: normally open relay interface 5. COM2: Common Interface Relays 6. NC2: normally closed relay interface   How to use:  By default, the relay is release, press the trigger button, the relay pull, press again, the relay release, the third press, the relay pull, and so on Typical applications: Automotive electronics Industrial equipment AC DC Motor LED lighting Smart Home / Home Automation Emergency lighting MCU AVR UNO MEGE2560 development board Toy car PLC
