Description
📌 FANUC A20B-0279-C041#TA / #TAS – Small 9″ Monochrome CRT/MDI Display Unit
General Description:
The A20B-0279-C041 is a 9-inch monochrome CRT (Cathode Ray Tube) display with MDI (Manual Data Input) functionality, used in FANUC CNC control units as the operator display and manual input interface for various control panels.
Suffix Meanings:
-
#TA – English-language display MDI unit (text in English).
-
#TAS – Symbol (icon) display MDI unit (uses symbolic/graphic indicators instead of full English text).
Where It’s Used:
This CRT/MDI unit is part of the A20B-0279 series of front-panel display modules in certain FANUC control systems — typically used in older generation CNCs that employ a monochrome CRT screen for the operator interface.
Typical Function:
-
Displays CNC status, messages, and machine feedback on a 9″ monochrome screen.
-
Provides MDI (Manual Data Input) capability — allowing the operator to enter and execute manual commands directly from the display unit.
-
Available in different UI variations depending on the suffix: English text (#TA) or symbolic display (#TAS).
Notes:
-
These units form part of the operator console/display assembly and connect to the CNC’s main electronics.
-
Because they are CRT-based, they are more common in older FANUC systems rather than newer LCD panels.
