16-Channel 5V Relay Module with Optocoupler

16-Channel 5V Relay Module with Optocoupler

Take full control of your large-scale automation projects with this massive 16-Channel 5V Relay Module. This board is the ultimate solution for applications requiring independent control over a large number of high-power devices, such as multi-zone smart home systems, complex industrial machinery, or elaborate interactive displays.

This module allows your low-power microcontroller, like an Arduino Mega or Raspberry Pi, to safely switch up to sixteen separate high-voltage AC or high-current DC loads. Each of the sixteen channels is equipped with a high-quality 10A relay and is individually isolated from your control circuit using an onboard optocoupler, providing maximum protection for your sensitive electronics.

Designed for robust and reliable performance, the board includes a dedicated power supply terminal and individual status LEDs for each of the sixteen relays, giving you clear visual feedback on the state of every channel.

Key Features:

• Channels: 16 (Independently Controllable)
• Control Signal Voltage: 5V TTL
• Max Load (AC): 10A at 250V AC per channel
• Max Load (DC): 10A at 30V DC per channel
• Full Isolation: Onboard optocouplers for each of the 16 channels
• Status Indicators: Individual status LEDs for each relay
• Power Supply: Requires a separate 5V power supply for the relays (JD-VCC)

Applications:

This 16-channel relay module is perfect for advanced and large-scale projects, including comprehensive home automation (controlling all lights and appliances in a home), industrial control panels, multi-channel robotics, automated agricultural systems (controlling multiple pumps and valves), and large stage/lighting effects.
