Large Current Relay Driver

This is a large current Relay module with single pole double throw switch which provides normally closed and normally open operations. The Relay is the most common used module in application such as home automation, industrial automation, and machine on/off. Sometimes you need to control large current such as the fans, lights, water heaters, room heaters, Air-conditioning, vacuum pumps That is what this Large Current Relay Module can be helpful to drive such high current load with just TTL signal. Easy interface with embedded systems and micro-controllers.
