Balboa Expander PCB's

Balboa Expander circuit boards are used with Balboa's GS and GL control systems. They are used to increase the capability of a specific control box such as adding an extra water pump or air blower.

Matching up the replacement Expander PCB is simple, find the white label that will be stuck directly on the board. This will have a 5 digit part number starting with the number 5, you will also see model the name on the label something like EXT 2RELAYS.
