Description
This is a 5V, 16-channel relay module with a light coupling LM2596S power supply. You will 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 5V 16-Channel Relay Interface Board, and each one of the individual relays needs 15-20 mA of driver current. The board features indication LED for Relay output status and a standard interface that can be controlled directly by many of widely used microcontrollers like Arduino, etc.
The 5V electromechanical relay module has an AC contact capacity of 250V and also includes 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 drives.
The LM2596S buck chip in this relay module shows a slight fever, which is a normal phenomenon as relays with long working hours have normal fever characteristics. 4 relays load power to leave some margin. They should avoid high power (about 2000 watts) and a long working environment, which will have some impact on the life of the product.
