Velleman K8015 Function Relay Switch, Multi-Colour

Velleman K8015 Function Relay Switch – Multi‑Colour

The Velleman K8015 is a compact, versatile relay module designed for hobbyists, educators and professionals who need reliable switching in a small footprint. It combines a robust mechanical design with an intuitive colour‑coded interface that makes wiring straightforward even for beginners.

Key Technical Specifications

• Input Voltage Range: 9 V to 12 V AC or DC (maximum current 2.5 A)
• Output Power: 230 V AC up to 5 A, or 12 V DC
• Dimensions: 87 mm × 39 mm × 26 mm – ideal for breadboards and small enclosures.
• Colour‑coded contacts: Blue, Green, White – each colour corresponds to a distinct function or output channel.
• Mounting type: Plug‑in module with screw terminals; can be mounted on a PCB or used directly from a breadboard.
• Package: “Kit à monter” (assembly kit) – includes the relay board, mounting hardware and a set of colour‑coded jumpers for quick configuration.

Design Features That Set It Apart

The K8015’s design focuses on ease of use without compromising performance:

• Colour Coding: The blue, green and white contacts are clearly marked, reducing wiring errors during assembly.
• High‑Quality Relays: Each channel uses a durable electromechanical relay capable of handling the specified output power safely.
• Compact Footprint: At just 87 mm long, it fits comfortably in most hobbyist projects and educational kits.
• Versatile Input Options: Accepts both AC and DC inputs within the same voltage range, making it suitable for a wide variety of power supplies.

Typical Applications

The K8015 is ideal for projects that require multiple independent switching functions from a single module. Common use cases include:

• Educational Demonstrations: Teaching students about AC/DC switching, load control and safety isolation.
• Prototype Development: Rapidly testing circuit designs where several outputs must be toggled independently.
• Home Automation: Controlling lights, fans or other appliances from a central microcontroller via relay outputs.
• Industrial Control Panels: Small‑scale control boards that need reliable switching for sensors and actuators.

Installation Guide

Setting up the K8015 is straightforward. Follow these steps to ensure a safe and functional installation:

1. Prepare Power Supply: Verify that your supply provides 9–12 V AC or DC, and that it can deliver at least 2.5 A.
2. Connect Input: Use the designated terminals on the module to connect the input voltage. The board’s markings indicate which pins are for AC and which for DC.
3. Configure Output Channels: Attach your load (lamp, motor, etc.) to one of the coloured output terminals. Ensure that the load does not exceed 230 V AC at 5 A or 12 V DC at the rated current.
4. Secure Mounting: If using a PCB, solder the module onto the board and secure it with screws. For breadboard use, simply plug the module in and connect jumper wires.
5. Test Operation: Apply power and toggle each channel to confirm that the relay activates correctly and that all connections are stable.

Safety Considerations

While the K8015 is designed for safety, users should observe standard electrical precautions:

• Never exceed the specified input voltage or output current limits.
• Ensure all connections are insulated and secure to prevent short circuits.
• When working with AC mains (230 V), use appropriate isolation techniques and avoid direct contact with live terminals.

Why Choose the Velleman K8015?

The combination of a small form factor, colour‑coded contacts, dual AC/DC input capability, and robust output handling makes the K8015 an excellent choice for anyone needing reliable multi‑function switching in a compact package. Its straightforward assembly kit format also means you can get started quickly without specialized tools or extensive wiring knowledge.

Conclusion

The Velleman K8015 Function Relay Switch is more than just a relay board; it’s a versatile, user‑friendly component that bridges the gap between complex control systems and simple hobby projects. Its thoughtful design ensures dependable performance while keeping installation hassle‑free.
