More features

• Wide Compatibility - This GLX-PCB-PRO main printed circuit board compatible with all ProLogic “P-4”, “PS-4”, “PS-8” and “PS-16” units. It supports equipment repair without the need to replace the whole controller. Align with original system structures for plug-and-play replacement and normal equipment operation.
• Complete Wiring Matching – The PCB is equipped with supporting orange, red and black wires. It is necessary to replace the matched wires together with the new board to avoid unexpected circuit faults. Users must cut off the power supply entirely before disassembly and installation, and wire strictly according to the circuit board color codes and printed text marks to achieve accurate and fast installation.
• Accurate Data Migration – Effective pre-installation preparation avoids data loss and equipment abnormality. Before your repair,please record all key programming information including configuration options, timer parameters and system setting data. Taking photos of the original wiring layout serves as an intuitive reference to help complete wiring restoration on the new PCB.
• Independent Circuit Protection – Three independent fuses are configured for targeted circuit protection to avoid overload and short-circuit problems. The 4A fuse corresponds to actuator circuit protection, the 3A fuse works for S+D circuit protection, and the 20A fuse is designed for chlorinator circuit protection.
• Standard Operational Adaptability – The targeted multi-circuit protection structure matches the operational logic of the units. It maintains consistent system running states after PCB replacement, realizing effective equipment repair and normal functional output.
