Zodiac – Expansion board ZS500 – R06930

The Zodiac Expansion Board ZS500 (R06930) is an electronic expansion module designed as a genuine spare part for Zodiac’s ZS500 pool automation and control systems. This PCB-based expansion board extends or restores the functional capacity of the ZS500 control unit, allowing the system to manage additional pool equipment outputs or communication channels. As an OEM replacement component, it is manufactured to the original electrical and dimensional specifications of the ZS500 platform, ensuring full compatibility and reliable integration without the need for modifications.

The expansion board slots directly into the ZS500 control unit housing, interfacing with the main controller to restore or add electronic functionality. It is a surface-mounted electronic assembly built for low-voltage pool automation environments. Using a genuine Zodiac replacement board ensures that the control unit’s programming, safety logic, and output management remain fully operational after installation. This is particularly important in automated pool systems where precise equipment scheduling, sensor feedback, and pump or valve control must function without interruption.

Características técnicas y compatibilidad

The R06930 expansion board is specifically engineered for use within the Zodiac ZS500 series controller ecosystem. It is a low-voltage electronic card designed to integrate seamlessly with the existing ZS500 main board and terminal architecture. Because this is a genuine OEM spare, it meets the original factory tolerances for signal levels, connector types, and board dimensions. Installation requires basic electronics handling care — in particular, protection against electrostatic discharge — and should be carried out by a qualified technician familiar with pool automation control systems. No soldering is required for standard replacement; the board connects via the system’s existing internal connectors.

Suitability and application

This expansion board is intended exclusively for pool installations running a Zodiac ZS500 automation controller. It is suitable for both residential and light commercial pool setups where the ZS500 system is used to manage filtration, heating, lighting, or additional pool equipment. If the ZS500 controller is showing faults related to its expansion outputs, or if the expansion board has been identified as faulty during diagnostic procedures, R06930 is the correct OEM replacement part. It is not compatible with other Zodiac controller series unless explicitly confirmed by the manufacturer’s compatibility documentation. Stocking this part is recommended for pool service professionals who regularly maintain ZS500-equipped installations.
