This is 5V 16Channel Relay interface board and each one of the individual relays needs 15-20mA Driver Current. The board features indication LED for Relay output status and the standard interface that can be controlled directly by many of widely used microcontrollers like Arduino etc.
The 5V electromechanical relay module with AC contact capacity of 250V which also include light coupling protection(optocoupler) for isolation of control circuitry. The plate load power module doesnt need an external power supply. It supports all SCM Drive.
The LM2596S buck chip in this relay module shows a slight fever which is a normal phenomenon as relays, long working hours have normal fever characteristics. 4 relay load power to give leave some margin, should avoid high-power (about 2000W) and long working environment, there will be some impact on the life of the product.
