YINGHUA

YINGHUA 5V 2-Channel Relay Module Shield built-in oven

SKU CH-BN8X-FXZMH

A 5 V two-channel relay shield for Arduino, ARM, PIC, AVR and DSP microcontrollers

  • 5V logic control for direct microcontroller connection
  • Two independent channels switch separate circuits simultaneously
  • Opto-isolated inputs protect sensitive control electronics
  • Standard shield layout fits common development boards

5V 2-Channel Relay Shield

This 5 V relay module provides two independently controlled channels for switching external circuits from a microcontroller. It is designed to plug directly onto Arduino-compatible boards and accepts logic-level signals from ARM, PIC, AVR or DSP platforms. Each channel uses an opto-isolated driver to protect the host controller from voltage spikes. The board arrives new and ready for breadboard or prototype use.

Makers needing two switched outputs

Builders who require more than two relays, higher coil voltages or integrated protection diodes should consider alternative modules. Projects that demand industrial-grade terminal blocks or DIN-rail mounting will not be satisfied by this compact shield. Users needing relay status LEDs on the main board must verify the layout separately.

Highlights

  • 5V logic control for direct microcontroller connection
  • Two independent channels switch separate circuits simultaneously
  • Opto-isolated inputs protect sensitive control electronics
  • Standard shield layout fits common development boards

Questions about this item

How can I verify the relay module is switching correctly after wiring it to my Arduino?

Apply 5 V to the VCC and GND pins, then drive each IN pin high; the corresponding LED should light and an audible click from the relay confirms the contacts have closed.

What comes in the package and do I need any extra components to use it with a microcontroller?

The package contains one 5 V 2-channel relay module shield with on-board optocouplers and terminal blocks; no extra parts are required for direct connection to an Arduino, ARM, PIC, AVR or DSP board.
