5V/3.3V Four Channel 10A Isolated Relay Module – 4 channel relay module (projectbazar)

Description

Relays are most commonly used switching devices used in electronics. It can be used to switch high current loads easily unlike transistors which are limited by the maximum current that can flow through them and also can’t switch AC loads. This 5V/3.3V Four Channel 10A Relay Module can switch both AC and DC loads. It is an Electromagnetic switch, when the coil inside is energized with a small current, it can switch ON or OFF the high current circuit. It has PCB screw terminals to directly connect. They can be used in Home automation to switch ON or OFF the appliances, in Electronic circuits to perform switching operations, in safety circuits to disconnect or connect the heavy loads in case of any dangerous situation, in Automobile applications like turning on windscreen wipers, power windows fuel pump, cooling fan etc.
