⚙️ Specification

Brand Balboa Water Group
Our part number G1900
Board model X-P
Function Expander (daughter) board — one 1-speed pump output
Replaces 53544 (X-P), no longer manufactured
Related part G1910 — the X-P231 high-amp 1-speed 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.

❓ X-P or X-P231?

The X-P (this board) switches a 1-speed pump output. The X-P231 (G1910) is the high-amp version, which Balboa’s EL2001 Mach 3 tech sheet describes as providing branch-circuit protection for a high-amp device. If you are replacing an existing board, match the model name printed on it.
