1-Channel Opto-isolated AC Input Detector Module (ACD1)
Original price was: 45.00 EGP.40.00 EGPCurrent price is: 40.00 EGP.
Single-channel AC voltage detector module with optocoupler isolation. Tells a microcontroller whether an AC mains line is present, safely isolated from the high voltage.
The 1-Channel Opto-isolated AC Input Detector Module (ACD1) detects the presence of AC voltage on one input and reports it to a microcontroller through an optocoupler. Because the mains side is optically isolated from the logic side, you can safely monitor lamps, pumps, doors or power failures with Arduino, ESP32 or a PLC.
1-Channel Opto-isolated AC Input Detector Module (ACD1) – Key Features
- 1 AC input detection channel
- Optocoupler isolation between AC and logic sides
- Digital output for microcontrollers
- Status LED
- Screw terminals for wiring
Applications
Makers, students and technicians use it in many kinds of projects, for example:
- Mains power failure detection
- Monitoring whether a pump, motor or lamp is on
- Smart home and IoT status inputs
- Connecting 220V switches to microcontrollers
- Zero-cross or AC presence detection
Usage Tips
Mains voltage is dangerous: wire the AC side with the power off and keep it covered. Check the AC input voltage range printed on the board, and keep the AC and logic wiring physically apart.
