Please Note: Discounted Due to Cosmetic Damage
This product is offered at a discounted price due to cosmetic damage incurred during transit from our suppliers. Cosmetic issues may include surface scratches, scuffed or dented packaging, or bent pins. These imperfections are purely cosmetic and do not affect the product’s functionality or performance.
If the product has bent pins, they can usually be straightened with care. Use a pair of needle-nose pliers or tweezers to gently bend each pin back into place, supporting the base of the pin to avoid stress on the component. Take your time and avoid excessive force.
All items have been visually inspected to ensure they are in full working order. This is an excellent option if you’re looking for a fully functional product at a reduced price and are willing to overlook minor visual flaws.
Sample images have been provided to illustrate the types of cosmetic damage that may be present. The actual condition of each item may vary—some may be in better or worse condition than shown. These images are intended for reference only to help visualise the nature of the damage.
Description:
The 16 Channel 5V Relay Module Low-Level Trigger Board is a versatile and powerful switching solution for microcontroller-based projects. Compatible with Arduino, Raspberry Pi, and other digital logic platforms, this module allows you to control high-voltage AC or DC loads with low-level digital signals. It’s ideal for applications in home automation, industrial control, and robotics where multiple relays are needed in a single, compact board.
Each of the 16 relays on the board is triggered using a low-level signal (active LOW), making integration with digital outputs straightforward. Additionally, the module features optocoupler isolation to provide protection and prevent high-voltage feedback from damaging your controller. Whether you’re switching lights, motors, fans, or solenoids, this board offers dependable performance, galvanic isolation, and onboard status LEDs to indicate relay states. With screw terminals for easy connection and a robust PCB design, this relay module is built for reliable switching in demanding environments.
