상품 특징
- This module provides four independent optocoupler isolation channels, allowing multiple digital signals to be transmitted while maintaining electrical isolation between input and output sides. It helps reduce interference and improves signal reliability in control systems.
- Supports a wide DC input signal range, typically from low-voltage logic levels to higher control voltages. This makes the module suitable for interfacing microcontrollers, PLCs, sensors, and other control devices operating at different voltage levels.
- Input and output circuits are electrically isolated through photoelectric coupling. This isolation helps protect low‑voltage control electronics from voltage spikes, noise, and ground potential differences in industrial or mixed‑signal environments.
- The optocoupler‑based design supports stable digital signal switching and reliable transmission. It is suitable for signal conditioning, level conversion, and isolation in automation, monitoring, and control applications.
- Compact board layout with clearly labeled terminals simplifies wiring and installation. The module is suitable for control cabinets, embedded systems, test platforms, and electronics development projects requiring isolated multi鈥慶hannel signal interfaces.
