5V 8Ch 10A Relay Module

Control up to eight AC or DC loads from a single microcontroller with this 5V 8-channel relay module. Each channel is driven by an 8550 transistor and can switch up to 10 A at 250 V AC or 30 V DC, making it a solid choice for home automation, robotics, and hobby builds that need more outputs than a board can drive directly.

The module runs on a 5 V supply and draws only 5 mA of trigger current, so it pairs comfortably with Arduino, Raspberry Pi, ESP32, and other single-chip controllers. Each channel has a jumper to select high-level or low-level triggering, and a fault-tolerant design keeps the relays from actuating if a control line is ever disconnected. A green power LED and eight red channel LEDs give you at-a-glance status.

The simple 3-wire control interface (VCC, GND, IN) connects directly to your microcontroller’s IO pins, and all wiring goes through screw terminal blocks for clean, secure connections. Fixed mounting bolt holes make it easy to install the module on a base plate or inside an enclosure.

• Operating voltage: DC 5 V
• Max load per channel: AC 250 V / 10 A, DC 30 V / 10 A
• Trigger current: 5 mA, with jumper-selectable high- or low-level triggering
• 8550 transistor drive, 8 red relay status LEDs, and a green power LED
• Fault-tolerant design: relays stay put if the control line is disconnected
• Screw-terminal wiring and fixed mounting bolt holes for easy installation
