WERLAHO GLX-PCB-PRO Replacement Main PCB for Hayward ProLogic Goldline — Upgraded Reliability, T-CELL Compatible

WERLAHO's upgraded GLX-PCB-PRO main PCB is a drop-in replacement circuit board designed to restore and improve the control functions of Hayward Goldline ProLogic and compatible AquaLogic automation systems.

If your pool automation panel has failed or is unreliable, this WERLAHO GLX-PCB-PRO replacement board is engineered to directly substitute the original Hayward ProLogic / Goldline main PCB and regain full system control quickly. The board matches the electrical connections and control functions of legacy PL-P-4, PL-PS-4, PL-PS-8, PL-PS-8-V, PL-PS-16, and PL-PS-16-V models while introducing hardware upgrades aimed at better handling inrush current, longer component life and a more stable supply for connected T-CELL chlorinators.

How does this replacement board improve reliability?

The WERLAHO GLX-PCB-PRO uses enhanced components where they matter most to reduce failures under heavy electrical load. Relay contact surfaces have larger silver areas to tolerate higher inrush currents, and a reverse-protection diode helps shield the power rail from transient spikes. Resistors have higher power ratings and electrolytic capacitors feature increased capacitance and voltage rating for steadier operation.

• Enlarged silver relay contacts to withstand stronger motor/startup currents
• Reverse-protection diode to reduce power-surge impact
• Higher-wattage resistors for longer service life
• Electrolytic capacitors rated up to 60V and with greater capacitance for improved power reserve

Will this board work with my ProLogic or Goldline automation?

The replacement is built for compatibility with a broad set of ProLogic and Goldline AquaLogic control panels, matching pinouts and control features so installers can swap it into existing enclosures. After installation you may need to access system menus to enable or reconfigure certain outputs such as pool lights or auxiliary relays, because internal parameters control those functions. All units are factory-tested to ensure they meet common functionality expectations.

• Compatible with PL-P-4, PL-PS-4, PL-PS-8, PL-PS-8-V, PL-PS-16, PL-PS-16-V models
• Works with T-CELL series chlorinators: T-CELL-3, T-CELL-5, T-CELL-9, T-CELL-15
• May require menu adjustments after installation to enable specific outputs
• Pre-tested before shipping to confirm basic operation

What practical benefits can I expect after replacing the PCB?

Replacing a faulty main PCB with the WERLAHO GLX-PCB-PRO restores automation control without the expense of a full system replacement and reduces repeat failures thanks to the upgraded parts. The improved power handling reduces stress on the supply and connected devices like chlorinators, which can lead to more stable chlorine generation and longer component life. Installation is straightforward for anyone comfortable with pool control wiring and standard safety precautions.

• Restores full automation functions quickly and affordably
• Reduces electrical stress on power supply and peripherals
• Helps prevent frequent board failures with upgraded components
• Compatible with common T-CELL chlorinators for continuous operation

Who is this replacement board for?

This WERLAHO GLX-PCB-PRO main PCB is aimed at pool technicians, DIY-savvy pool owners, and service shops who need a reliable, cost-effective replacement for failed Hayward ProLogic or Goldline AquaLogic main boards. It is particularly useful when the original board has stopped responding, relays have become unreliable, or you want an upgraded component set to better tolerate demanding electrical loads. Note: installers should follow safety procedures, verify compatibility with their specific panel model, and reconfigure internal menu settings as needed after fitting the board.
