Description:
2 Channel DC 12V Self-locking Relay Module(version 4) :
Working voltage: DC 6-24V(Recommended DC 9V 12V)
Working current: 1 relay 70MA;2 relay 140MA;
Standby current: 0.25mA
Load current : AC 250V/10A, DC 30V/10A
Trigger mode: Low pulse trigger
Size: 48mm * 32.3mm * 18.5mm (L * W * H), Very small size
Weight: 27.6 g
USE 1:
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.
USE 2:
By default, the relay is release, MCU output low-pulse(0.3-1seconds), the relay pull, low-pulse again, the relay release, the third low-pulse, the relay pull, and so on.
Module interface:
1. V: positive power supply (VCC)
2. G: negative power supply (GND)
3. T (T1/T2/T3/T4): Low pulse trigger
Relay outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface
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
