12V 2-Channel Relay Module with Optocoupler
Command heavy-duty high-voltage mains machinery safely with the premium 12V 2-Channel Relay Module with Optocoupler. Explicitly engineered to provide bulletproof isolation between your delicate logic circuitry and large electrical loads, this dual-channel power switch features independent onboard optocouplers to block reverse electromagnetic interference (EMI) and high-voltage spikes. Capable of switching up to 10A at 250V AC or 30V DC, each relay is driven by a highly stable transistor network using a standard low-level logic trigger. Outfitted with an integrated JD-VCC jumper configuration that lets you separate the microchip power from the electromagnetic coils completely, it serves as the definitive hardware component choice for constructing smart home automated light switches, industrial PLC overrides, autonomous water pump timers, CNC spindle triggers, and custom DIY power distribution boards.
