High Load Capacity for Versatile Use: Equipped with genuine quality relays, this module supports a maximum load of AC 250V/10A and DC 30V/10A, making it ideal for controlling high-power devices in Arduino projects, from motors to lighting systems.
Stable SMD Optocoupler Isolation: Features surface-mount device (SMD) optocoupler isolation technology, ensuring strong driving capability and reliable performance. With a low 5mA trigger current, it minimizes power consumption while maintaining signal integrity.
Flexible Trigger Modes: Configurable via jumper to support both high-level and low-level triggering, adapting to diverse Arduino programming needs. Perfect for custom automation, robotics, or home control setups.
Safety-Focused Fault-Tolerant Design: Engineered with fault tolerance—even if the control line is accidentally disconnected, the relay remains inactive, preventing unexpected circuit activation and protecting your devices.
User-Friendly Interface & Clear Indicators: Includes a terminal block for direct, hassle-free wiring. Monitor operation at a glance with a green power indicator (steady when powered) and a red relay status indicator (lights up when activated), simplifying troubleshooting and testing.
