AJMRTC 8-channel relay expansion board is designed for Raspberry Pi and Jetson Nano. It adopts SPDT relays with normally open and normally closed contacts, supporting high-power AC and DC loads. Each channel only draws 6mA coil current, which is friendly for GPIO control. Built-in photocoupler isolation blocks high-voltage interference and protects your mainboard. It comes with screw terminals for easy wiring and onboard status LEDs for visual relay indication. It is widely used for smart home automation, light control, motor switching, pump control and industrial embedded automation projects.
