Description
This serial controlled Relay Module provides a simple way to connect a relay up to your Arduino, AVR, PIC or Raspberry Pi project. Controlled via a 5-12V TTL signal, this relay is designed for switching loads of up to 220VAC. Included on the board is an LED power indicator.
Commonly used in IoT projects to control lights and other electronic appliances.
Specifications:
The Relay Module consist of a 1MΩ resistor, a LED, a 1N4007 rectifier diode and a 5VDC relay capable of handling up to 250VAC and 10A.
On the DC side of the board there are 3 pins for signal, power and ground. On the AC side there are 3 contacts, NC (Normally Closed), Common and NO (Normally Open).
