Safe & Stable Isolation Design – Built-in optocoupler isolation protects microcontrollers (Arduino, ESP8266, etc.) from voltage spikes, surges, and electromagnetic interference.
Dual Trigger Modes – Supports both high-level and low-level triggering (jumper-selectable) for flexible compatibility with 3.3V/5V control systems.
8 Independent Channels – Control up to 8 devices (AC 250V/10A or DC 30V/10A) simultaneously, ideal for smart homes, irrigation systems, or industrial automation.
LED Status Indicators – Clear visual feedback for each relay's on/off state. Includes screw terminals for secure wiring and DIN rail mounting support.
Plug-and-Play Compatibility – Pre-soldered headers and labeled pins (VCC, GND, IN1–IN8) for quick integration with breadboards, PLCs, or IoT projects.
