An 8-channel relay module is an electronic board with eight individual relays, allowing a microcontroller (like Arduino or Raspberry Pi) to switch eight different high-power devices (lights, motors, etc.) independently, safely isolating the low-voltage control circuit from the high-voltage load. These modules feature opto-isolation for safety, LEDs for status, and can handle loads up to 10A at 250VAC/30VDC, connecting via standard digital pins and supporting 5V control signals, with jumpers to select between TTL/CMOS or ground triggering.�
Each relay needs 15-20mA driver current.
Equipped with high-current relay : DC30V 10A,AC250V 10A,125VAC 15A
Each relay has normally open and normally closed contact.
The 8 channels are optically isolated, safe, reliable, anti-interference.
Can be selected by jumper relay and TTL or ground.
With power indicator,each channel has a status indicator.
This item is a 5V 8-Channel Relay interface board,It can be controlled directly by microcontrollers such as Arduino, AVR, PIC, ARM and so on.
It is widely adopted in devices of power protection, automation technology, sport, remote control, reconnaissance and communication, as well as in devices of electro-mechanics and power electronics.
