2PCS 2-Channel 12V Relay Module with Optocoupler Isolation – High/Low Level Trigger Control for Arduino, Raspberry Pi, PLC – Industrial Automation, Smart Home DIY (Supports AC/DC Loads)

• 12V System Compatibility – Designed for 12V DC power applications, perfect for automotive electronics, solar systems, trucks, and industrial equipment.
• Enhanced Safety with Optocoupler – Optically isolated relays protect microcontrollers (Arduino, Raspberry Pi, ESP32) from voltage surges and EMI, ensuring stable operation.
• Dual Trigger Flexibility – Jumper-selectable high/low level triggering (3.3V–12V compatible) to match diverse control logic requirements.
• High Power Handling – Each relay supports up to 10A 250V AC or 10A 30V DC loads, ideal for motors, lights, pumps, or HVAC systems.
• Easy Installation & Monitoring – Screw terminals for secure wiring, LED status indicators per channel, and DIN rail mounting support for industrial setups.
