Description
FANUC A14L-0132-0001#B is an inverter printed circuit board used in FANUC CNC display units — specifically for the 10.4-inch LCD panel backlight/inverter section of PANEL i or PC-type displays. It is a variant (the #B revision) of the base A14L-0132-0001 part suited to later or different LCD display hardware within compatible FANUC systems.
🧠 Function
-
Role: It’s an inverter PCB (printed circuit board) that generates the necessary power to drive the backlight of a 10.4″ LCD display in a FANUC controller’s operator panel.
-
Application: Found inside the display assembly of various FANUC CNC PANEL i or PC-based screens. It’s an internal component, not a standalone device — if the backlight or display power stage fails, this board may need replacement or repair.
🧩 What the “#B” Means
-
The #B in the part number distinguishes a revision or updated variant of the original A14L-0132-0001 board. Revision codes like #A, #B, etc., in FANUC part numbers often indicate design updates or compatibility changes for newer batches of hardware or specific basic unit ranges.
-
According to FANUC maintenance manuals, A14L-0132-0001#B is specifically listed as the inverter PCB for 10.4″ LCD types in later basic unit ranges (e.g., A08B-0082-B031 to B038, B041 to B048, etc.).
