5V 4 Channel Relay Board - 4-Channel Relay Module

The 4-channel relay control board is a relay board that can control contacts with 5V, usable with Arduino or other microcontrollers.
It draws a current of 20mA during the trigger signal from the microcontroller. It is frequently used in various hobby, industrial, and robotic projects.
It can switch currents up to 10A at 30VDC or 220VAC voltage. There are control LEDs for each relay.
