⚙️ Specification

Brand Balboa Water Group
Our part number G1920
Board model X-P332
Function Expander (daughter) board — second 2-speed pump output
Supplied with 30A fuse and new mounting hardware
Replaces 55137 (X-P332), no longer manufactured
Also available as G1930 — the BP-series 12A version

⚠️ This is an expander (daughter) board, not a standalone control board. It mounts inside the spa control box alongside a compatible main board and adds one extra pump output. It cannot run a spa on its own.

📋 Which systems use the X-P332

Balboa’s own tech sheets name “X-P332 PN 55137” on the VS520Z, VS520SZ, VS520DZ, VS523DZ and VS525Z systems, and list “Expander PCBA: 55137” in the replacement parts of the legacy BP501G2, BP501G3, BP2000G1, BP2100G1, BP21MS2B, BP21MS3B, BP21P4BC, BP20P4BC, BP6013G2 and BP6013G3 revisions. On the current revisions of those systems, and on the BP7, Balboa list expander 59097 instead. If you are not sure which revision you have, send us the part number from your main board and we will tell you which expander it takes.

❓ Which one do I need, G1920 or G1930?

The G1920 is the 2-speed X-P332 for VS520-series main boards. The G1930 is the BP-series version, rated 12A. Our supplier’s description lists the G1920 for VS520SZ, VS520DZ, BP7 and BP501 systems; Balboa’s current BP7 tech sheet lists expander 59097. If your main board is a BP-series board, check its tech sheet or ask us before ordering — we would rather get it right than take the order twice.
