5V 16 Channel Relay Module with Light Coupling LM2576 Power Supply
This is a 5V 16 Channel Relay Module with Light Coupling LM2596S Power Supply, Be 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 5V 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.
