Overcurrent protection sensor module 5A AC current detection sensor DC 12V relay module.

the detail information of product

1. Description: It is an overcurrent protection sensor
module . It uses a current transformer to collect the AC signal and realize the relay signal output after overcurrent within the range of 0-5A. The relay pulls in when there is overcurrent, and the relay is released when there is no overcurrent. The user can use the COM, NC and NO ports of the relay to control the external circuit to turn on and off, so as to realize the overcurrent protection function.

2. Features:
1).It uses an external LM2596 plug-in heat sink, which can withstand high current operation.
2).The input uses a 4A rectifier bridge to supply AC power, and has a dedicated DC input port, which is commonly used for AC and DC input.
3).The output voltage can be adjusted, from 3.3V to 30V.

13).Size: 44*38*35mm

4.Connection interface:
1.VCC: positive working voltage
2.GND: negative working voltage
3.ON: Normally open, before the relay is closed, NO and COM are disconnected, and connected after closing.
4.COM: Common terminal, common interface of the relay.
5.NC: Normally closed, before the relay is closed, NC is connected to COM, and disconnected after closing.

Conclusion

With the instructions above, you can set up an overcurrent protection system using sensors and relays. This system will help protect your electrical devices from overcurrent conditions by automatically activating or deactivating the devices when the current exceeds the set threshold.
