2-Channel AC Detector Module (50~250VAC)
2.50 $
ACD2-HV is an isolated AC voltage detection module designed to detect the presence of 50–250 VAC and provide an isolated 3–24 V active-high output for interfacing with microcontrollers, PLCs, and other low-voltage control systems. Optical isolation using a PC817 optocoupler, together with PCB isolation slots, provides electrical separation between the high-voltage input and low-voltage output. An onboard LED indicates the presence of AC voltage.
Features:
- Detects 50–250 VAC input voltage.
- 3–24 VDC active-high output.
- Compatible with 3.3 V, 5 V, 12 V and 24 V control systems.
- Capacitive AC input for low power dissipation and reduced heat generation.
- Optical isolation.
- LED indication of AC presence.
- Screw terminal connections for AC input and DC output.
- Mounting holes compatible with DIN rail adapters.
- Dimensions: 50 X 46.9mm.
