HiLetgo Electromechanical Relays Editorial Review

This HiLetgo Relay Module is made up of two pieces with high-level triggers and opto-isolation. It can switch up to 10A at 250VAC, 125VAC, 30VDC, or 28VDC, and it works from 5V DC. The relay switches to a usually closed (NC) or usually open (NO) contact depending on the input signal. It is not a latching relay. Overall, the module appears to be reliable, cost-effective, and easy-to-use although some customers have received defective units.
