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-Channel Relay interface board and each one of the individual relays needs 15-20mA Driver Current. The board features an indication LED for Relay output status and the standard interface that can be controlled directly by many widely used microcontrollers like Arduino etc.
The 12V electromechanical relay module with an 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 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. 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.

Applications:
- Widely used for all MCU control
- Industrial sector
- PLC control
- Smart home control.

1. Where can I use the 16 Channel 12V relay module?
- This is a 12V 16-Channel Relay interface board, that can be able to control any electric appliances rated at under 2000 Watts. It supports all MCU control, industrial sector, PLC control, and smart home control.
2. How is a relay controlled?
- Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized.
3. What is a relay board?
- Relay boards are computer boards with an array of relays and switches. They have input and output terminals and are designed to control the voltage supply. Relay boards provide independently programmable, real-time control for each of several onboard relay channels.
4. What is the 16 Channel 12V relay module?
- The 12V 16 Channel Relay Module can control various appliances and other equipment with a large current. It can be controlled directly by a Micro-controller. The board features an indication LED for Relay output status and the standard interface that can be controlled directly by many widely used microcontrollers like Arduino etc.
5. What is an optocoupler in a relay?
- An optocoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits
