The AC Current Detection Relay Protection Module with 12V relay is designed for reliable overcurrent protection in AC circuits. Operating on DC 12V with low power consumption, it detects AC current within a 20Hz–400Hz range and provides a switch signal output.
When overcurrent is detected, the relay activates to protect connected devices; once normal conditions return, the relay releases automatically. The module supports up to 5A protection and features COM, NO, and NC relay terminals for flexible circuit control. With compact mounting dimensions and wide temperature tolerance, it is ideal for motor protection, short circuit detection, and intelligent automation applications.
Features:
- Operates on stable DC 12V power supply
- Supports AC frequency detection range of 20Hz–400Hz
- Built-in 5A relay for overcurrent protection
- COM, NO, and NC relay output terminals
- Low operating current (<20mA)
- Automatic relay trigger during overcurrent
- Compact PCB with easy mounting holes
- Wide operating temperature range (-40°C to +85°C)
