16 Channel 12V Relay Module Board

This is a 12V 16 Channel Relay Module with Light Coupling LM2576 Power Supply, Be able to control various appliances and other equipment with a large current. It can be controlled directly by a Microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic).

This is a 12V 16-ChannelRelayinterface board and each one of the individual relays needs 15-20mA Driver Current. The board features an indicationLEDfor Relay output status and the standard interface that can be controlled directly by many widely used microcontrollers likeArduinoetc.

The 12Velectromechanical relay modulewith an 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 drives.

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. 4relayload 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.
