This is a 12V 16 Channel Relay Module with Light Coupling LM2576 Power Supply, its able to control various appliances and other equipment with a large current. It can be controlled directly by Micro-controller (Arduino, 8051, AVR, PIC , DSP, ARM, MSP430, TTL logic).
This is 12V 16-Channel 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 12V 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 doesn’t 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.
