Opto-isolated AC Input Detector Module 4 Channel ACD4

From the shop's description

Opto-isolated AC Input Detector Module 4 Channel ACD4 The Opto-Isolated AC Input Detector Module (ACD4) is a four-channel interface board designed to detect AC voltage signals while providing complete electrical isolation between the input and output circuits. Using optocoupler technology, the module converts high-voltage AC signals into low-voltage logic signals that can be safely monitored by electronic control systems. Each channel operates independently, allowing multiple AC sources to be monitored simultaneously. The module is ideal for industrial automation, power monitoring, and smart control applications where the presence or absence of AC voltage must be detected without exposing sensitive control electronics to dangerous voltage levels. The onboard LED indicators provide a quick visual indication of the input status, while the terminal and pin header design simplifies installation and integration into existing systems. Features: Four independent AC input detection channels. Optically isolated inputs for improved safety. Built-in LED indicators for each channel. High noise immunity. Reliable AC voltage detection. Suitable for industrial control systems. Easy integration with microcontrollers and PLCs. Terminal block input connections. Pin header output interface. Compact PCB design. Simple installation with mounting holes.
