Mini 3A Relay Unit

PRODUCT DETAILS Description RELAY is a relay unit that allows you to control the on/off state of circuits operating at the DC/3A-30V or AC/3A-220V levels. It functions as an automatic switch, where a small current controls the operation of a larger current. In electrical circuits, relays play a role in automatic regulation, safety protection, and circuit switching.The RELAY unit provides three pins: ON, OFF, and COM. By programming the GPIO (General Purpose Input/Output) pins of your microcontroller or device to output high or low voltage levels, you can control the relay. The common terminal, COM, is connected to either the ON or OFF terminal to control the circuit's state.RELAY units are commonly used in applications where there is a need to control higher power loads or switch between different electrical systems. By using the RELAY unit, you can automate the control of circuits and ensure the safety and efficiency of your electrical projects. Product Features Single-BUS control Up to 3A @ 30 V DC or 220 V AC Software Development Platform: Arduino, UIFlow (Blockly, Python) Two Lego-compatible holes Include 1x RELAY Unit 1x Grove Cable 1x 3.96 socket Applications Remote control of high-power appliances, such as refrigerators, air conditioners, TVs, etc. Specification Resources Parameter Net weight 12g Gross weight 26g Product Size 48*24*21mm Package Size 60*57*17mm LEARN AND DOCUMENTS DOCUMENTS Automation with SIM800L ESP32 M5Stack Automation with SIM800L ESP32 M5Stack It is possible to turn a lamp or fan on and off through an SMS message.
