Yes, you can extend cables.

When extending cables, consider using high-quality extension cords or cables suitable for the intended purpose.

Consult relevant regulations or standards to ensure compliance with safety and performance requirements.

You can choose to extend:

To extend signal cables effectively:

Use high-quality extension cables designed for signal transmission to maintain signal integrity.
Use connectors suitable for the specific type of signal cable to ensure a secure and reliable connection.
Keep cable lengths within recommended limits to prevent signal degradation. For networking cables, this is usually <100m. For other signal cables, this is around 5m unless shielding is used.
Choose shielded cables to minimise interference and maintain signal quality, especially in areas with high electromagnetic interference.
Avoid running signal cables parallel to power cables to minimise electromagnetic interference.

To extend DC power cables effectively:

Use appropriate wire gauge that can handle the current without significant voltage drop. Refer to a wire gauge chart for guidance (use 12v 1A).
Be mindful of the cable length, as longer cables can lead to voltage drop. If significant length is needed, consider a higher gauge wire.
Maintain polarity: Ensure consistent polarity when extending DC power cables with tight connectors. Match positive to positive and negative to negative.
Employ insulated cables and provide protection against physical damage, ensuring the integrity of the power supply.
Always test the extended DC power system to confirm no short circuits and that the valve operates without overloading the power capacity of the supply.
