Relay 12V (5 Pins)

Relay 12V (5 Pins) is a high-quality electronic component designed for Arduino, prototyping, and educational electronics.

A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple control signals, and a set of operating contact terminals. The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof.

Relay Pin Configuration

Pin Number
Pin Name
Description

1
Coil End 1
Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground

2
Coil End 2
Used to trigger(On/Off) the Relay, Normally one end is connected to 12V and the other end to ground

3
Common (COM)
Common is connected to one End of the Load that is to be controlled

4
Normally Close (NC)
The other end of the load is either connected to NO or NC. If connected to NC the load remains connected before trigger

5
Normally Open (NO)
The other end of the load is either connected to NO or NC. If connected to NO the load remains disconnected before trigger
