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 24V and the other end to ground |
| 2 | Coil End 2 | Used to trigger(On/Off) the Relay, Normally one end is connected to 24V 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 |
