Traditions (Generic) 4-way relay module 12V 24V 16A BMZ-04K1 computer power cord

SKU CH-ZNCV-YAK8M

A four-channel relay module accepts 12 V or 24 V input and switches loads up to 16 A per channel

  • Controls four independent circuits with a single module
  • Operates on 12V or 24V input voltage
  • Each relay handles up to 16A switching current
  • BMZ-04K1 model designed for computer power cord applications

4-way 12V 24V relay module

This new module provides four independent relay channels that accept 12 V or 24 V control signals. Each channel is rated for 16 A switching capacity. The BMZ-04K1 design suits automation projects, test rigs and custom power-control builds that need multiple isolated outputs from a single board.

Replaces individual relay boards

Instead of wiring several single-channel relays, this unit consolidates four channels into one compact footprint. The jump is worth it when a project demands simultaneous switching of multiple loads at 12 V or 24 V and board space or wiring simplicity are priorities.

Questions about this item

What mounting holes or brackets does the 4-way relay module BMZ-04K1 provide for installation?

The module has four mounting holes on the PCB corners for M3 screws.

How do I wire the 12V or 24V input to the relay coil terminals and what is the common mistake?

Connect the 12V or 24V supply to the VCC and GND pins; the step often missed is adding a flyback diode across each coil to protect the driver.
