1 Channel 5v Optocoupler Isolated Relay Module

This is a 5V 1-Channel Optical Isolated Relay Interface Board, be able to control various appliances, and other equipment with large current. The 5V relay module circuit, each one needs 15mA-20mA driver current and equipped with high current relay: DC 30V / 10A, AC 250V / 10A. The 1-channel relay module uses genuine high quality DC5V relay and SMD opto-isolator supporting high/low level trigger, widely apply to control various AC/DC appliances, and other devices with large current. Optocoupler Relay Module can be controlled directly by micro-controller, home alarm system

Features Of 1 Channel Relay Module Board Shield with Optocoupler Support High and Low-Level Trigger for Arduino:

• Fault-tolerant design, even if the control line is broken, the relay will not trigger accidentally
