Traditions 16 Channel Relay Module Computer Power Cord

SKU CH-F6QP-ZSCBZ

A 16-channel relay module with optocoupler isolation for 5 V and 12 V ARM DSP control

  • 16-channel relay module controls multiple circuits
  • Optocoupler isolation protects the control side
  • Supports both 5 V and 12 V operation
  • ARM DSP controller handles switching logic

16-Channel Relay Module

This module provides sixteen independently switchable channels driven by an ARM DSP controller. It accepts both 5 V and 12 V supply rails and uses optocoupler isolation to protect the control side from load transients. The board suits automation projects that require multiple galvanically separated outputs.

Integration and Power Requirements

The unit needs a stable 5 V or 12 V source capable of supplying the combined coil current for all active channels. Wiring each channel to its load completes the switching path while the optocouplers keep the microcontroller ground separate. Builders who need more than sixteen channels or a different control voltage must select another module.

Highlights

  • 16-channel relay module controls multiple circuits
  • Optocoupler isolation protects the control side
  • Supports both 5 V and 12 V operation
  • ARM DSP controller handles switching logic

Questions about this item

What limits the 16-channel relay board during continuous operation?

The optocoupler isolation on each channel protects the control side from voltage spikes while the relays switch loads.

How much heat does the 12 V relay module produce when running all day?

Each relay draws only its coil current, so the board stays cool enough for enclosed cabinets without extra cooling.
