Zodiac – Multiplex interface board RS485 – R0570200

The Zodiac R0570200 is a Multiplex Interface Board with RS485 communication protocol, designed as a genuine replacement component for Zodiac pool automation and control systems. This board acts as the communication backbone between the main control unit and the various connected pool equipment devices, enabling reliable data transfer across the RS485 bus architecture used in Zodiac’s AquaLink TRi and compatible automation platforms.

The RS485 interface standard is widely used in industrial and pool automation environments due to its robustness over longer cable runs and its ability to support multiple devices on a single communication line. This makes it particularly well suited to pool installations where the control panel, pumps, lights, heaters, and chlorinators need to communicate efficiently without signal degradation. The multiplex function of this board allows it to manage and coordinate signals from multiple peripheral devices simultaneously, reducing wiring complexity and improving system reliability.

Technical characteristics and compatibility

The R0570200 Multiplex Board is engineered to integrate directly into Zodiac automation systems that utilise the RS485 serial communication standard. It is a factory-matched spare component intended to restore full functionality to a system where the original board has failed or been damaged. The board is designed for installation within the existing Zodiac control enclosure and connects to the system’s wiring harness using the original connectors. As a Zodiac OEM part, it ensures full electrical and software compatibility with the parent system, avoiding the risks associated with third-party substitutes.

According to available catalogue and distributor data, this part is listed under Zodiac’s pool equipment range and is available as a stocked spare component. Installation should be carried out by a qualified pool technician or electrician familiar with Zodiac automation systems, as the board interfaces directly with the pool’s low-voltage control electronics.

Suitability and application

This multiplex board is intended for use as a direct replacement part in Zodiac pool control systems that incorporate RS485 communication, including installations built around the AquaLink TRi platform and related Zodiac multiplex-compatible systems. It is suitable for both residential and commercial pool installations where Zodiac automation is already in place. This is not a standalone product and has no function outside of its parent Zodiac control system. It is the correct choice when diagnosing a communication fault or board failure within an existing Zodiac RS485 multiplex installation and a like-for-like OEM replacement is required.
