    12V 8-Channel Relay Module, Optocoupler Isolation, 10A

    • Industrial-Grade Switching Capacity: 8 relays rated for 10A 250VAC or 10A 30VDC loads, supporting motors/heaters up to 2000W per channel.
    • Optocoupler Isolation & Dual Trigger: SMD optocouplers (3,750Vrms isolation) with jumper-selectable high/low level control (5mA trigger current).
    • Fail-Safe Protection: Relays remain de-energized during signal wire breaks; anti-surge design protects microcontrollers.
    • Real-Time Status Monitoring: Green power LED + 8 red relay indicators; 141.5×50×18.5mm PCB with 4× M3 mounting holes (136×44.5mm pitch).
    • Plug-and-Play Wiring: Screw terminals for 12V power (DC+/DC-) and IN1-IN8 control signals; NO/COM/NC outputs pre-labeled.
