1 Pcs DC 5V 1 2 4 8 Channel Relay Module Optocoupler Isolation High Low Level Trigger Switch Control Board Power Expansion Microcontroller Device for IoT Smart Home Automation Robotics Maker DIY

Engineered to handle serious electrical loads. Each independent relay channel is equipped with premium components capable of safely driving maximum loads up to AC 250V/10A and DC 30V/10A, perfect for controlling heavy motors, heaters, and home appliances.
Safety is our top priority. Integrated with high quality SMD optocouplers, this module provides superior electrical isolation between the control and load circuits, effectively preventing high voltage surges from damaging your fragile microcontrollers.
Highly adaptable to any logic system. Designed with user configurable jumper caps, allowing you to easily set each relay channel to respond to either a high level or low level trigger based on your specific programming and circuit requirements.
Features standard Normally Open (NO) and Normally Closed (NC) interfaces for safe fail over operations. Additionally, the built in LED indicators provide instant visual feedback on power supply and individual relay activation status at a glance.
Operating on a standard DC 5V power supply, this control board requires minimal driving current. It is the perfect foundational hardware for custom IoT setups, smart home automation, robotics, and complex DIY electronic prototyping.
