Traditions (Generic) 16 Channel Relay Module 12V LM2576

SKU CH-2K2Y-C81DE

A 12 V relay board with 16 optically isolated channels and an LM2576 regulator

  • 16 channels switch multiple circuits from one board
  • 12 V supply simplifies integration with common power sources
  • LM2576 regulator delivers stable voltage to the relay array
  • Optocoupler isolation protects the control side from load transients

16-Channel 12V Relay Module

This 16-channel relay module operates at 12 volts and includes an LM2576 voltage regulator alongside optocoupler isolation. It functions as an expansion board for switching multiple loads in automation or control projects. Each channel provides a triggered switch contact for external circuits. The board suits hobbyists and engineers building multi-channel switching systems.

Check power and signal requirements

Verify that your controller can supply a stable 12 V source capable of driving all sixteen relays simultaneously. Confirm the logic-level voltage of your microcontroller matches the optocoupler input specifications. Ensure wiring and terminal blocks can handle the expected load current for each channel. Buyers needing more than sixteen switched circuits should consider a different solution.

Questions about this item

Does the 16 channel relay module include the 12V LM2576 power supply or must it be purchased separately?

The 16 channel relay module is supplied as a trigger board with optocoupler; the 12V LM2576 regulator is part of the board design so no separate power supply is required.

Should I choose the 16 channel version or a smaller relay count for a 12V LM2576 project?

Select the 16 channel relay module when you need to switch up to sixteen independent circuits from a single 12V LM2576 board.
