Description
š FANUC Part: A20B-2100-0411 ā Description
Part Name: A20B-2100-0411
Description: Connector Panel I/O Expansion Module B PCB ā a printed circuit board (PCB) used in FANUC CNC/automation control systems.
š§© Function & Role
-
It is part of the A20B-2100 series of I/O and connector interface boards for FANUC controllers.
-
Specifically, Expansion Module B means it provides additional input/output connectivity beyond the basic connector panel I/O module, extending the electrical interface for signals and wiring connected to the CNC or automation controller.
-
This board is typically mounted in the control cabinet and used where expanded I/O points are needed for peripheral devices, operator panels, sensors, actuators, or manual pulse generator (MPG) interfaces (in configurations without MPG on this specific variant).
š Typical Use Case
-
Installed inside industrial CNC machines or automation equipment that use FANUC modular controller systems.
-
Facilitates routing of expanded I/O signals from external devices into the FANUC controller logic.
š Key Details
-
Series: A20B-2100 (Connector Panel / I/O interface family)
-
Module Type: Expansion I/O Module B PCB (for expanded I/O connectivity)
-
Some listings note this board is without manual pulse generator (MPG) supports, meaning it focuses on general I/O expansion.
