5V Two-Channel Relay Modulel

5v two-channel relay module
the 5v two-channel relay module is an electronic switch that allows you to control high-voltage devices (such as lamps, motors, and home appliances) using low-voltage signals from microcontrollers like arduino, raspberry pi, or other control systems. each channel on the module controls a relay that can switch on/off a device, acting as an interface between low voltage control circuits and high voltage load circuits. the module operates at 5v, and it features opto-isolation to protect the control circuit from spikes and electrical noise in the load circuit.

this module is widely used in home automation, robotics, and industrial control systems for controlling ac or dc devices with ease. the relays on this module are typically rated for both ac and dc load control.
