Eight Channel 5V Relay Module With Opto Isolated Architecture And SMD Optocoupler Isolation Supports High And Low Level Trigger Hobbyist Friendly Project Ready Compatible With Arduino Raspberry Pi And Other DIY Projects
✔️ 8-channel 5V relay board with opto-isolated inputs and dual trigger options
This 8-channel 5V relay board uses opto-isolated inputs to safely switch eight loads from microcontrollers like Arduino or Raspberry Pi. It’s ideal for hobbyist automation, home projects, and DIY control panels where you need to drive mains or DC loads up to 250V AC/10A or 30V DC/10A with protection and clean signal separation. The board supports high or low level triggering per channel via jumpers and is built with durable SMD optocouplers for stable performance. It measures about 141.5x50x18.5 mm with four mounting holes for easy panel mounting.
✅ 5V/9V/12V/24V options for module voltage
✅ 8 channels with NO/COM/NC outputs
✅ Maximum load: AC 250V/10A, DC 30V/10A
✅ High and low level trigger selectable per channel
✅ Fault-tolerant design keeps relays from energizing if control line breaks
✅ Green power indicator and red 8-channel status indicators
✅ Size: 141.5mm x 50mm x 18.5mm; four mounting holes, 3.1mm diameter
✅ Direct terminal wiring interface for easy connection
