Description
The HKD 16-Channel Relay Module is a robust and reliable switching board designed to control high-voltage devices using low-voltage digital signals. Each relay is opto-isolated, providing effective protection for your microcontroller or control board. Operating at 5V logic, it is compatible with a wide range of platforms including Arduino, 8051, AVR, PIC, ARM, DSP, MSP430, and other TTL logic systems.
With the ability to switch both AC and DC loads up to 250V AC or 30V DC at 10A, this board is ideal for controlling home appliances, lighting, motors, or any other electrical devices. Each relay channel includes an LED indicator for visual status feedback and is activated by a high-level trigger signal.
Key Features
- 16 Independent Relay Channels
Control up to 16 devices from a single microcontroller - High Current Handling
Supports up to 10A at 250V AC or 10A at 30V DC - Opto-Isolated Inputs
