The 12V Dual Channel Relay Module with Light Coupling operates by using optical coupling isolation to ensure safety and reliability. It features high-current relays that can control both AC and DC appliances. The module is triggered by high-level signals and provides clear relay operation instructions.
Do not exceed the specified operating voltage of 12VDC.
Avoid using low-level trigger signals for triggering the relay.
Do not connect incompatible loads that exceed the relay's switching capabilities.
Connect power supply to the positive terminal (VCC) and power negative to GND for proper operation.
Use high-level trigger signals for effective relay triggering.
Utilize the provided screw terminals (C, NC, NO) for easy and secure wiring connections.
