The FANUC A20B-2102-0050 is an E-STOP PCB used in compatible FANUC robot control systems.

This control board supports the robot controller’s emergency-stop circuit by handling related safety signals and communication within the control system. It is commonly described as an E-STOP PCB, emergency-stop control board, or FANUC robot safety PCB.

The A20B-2102-0050 is part of the A20B-2102 series and is suitable for replacing an original board with confirmed emergency-stop circuit faults, damaged components, unstable signals, or communication problems.

The A20B-2102-0050 has been discontinued by the manufacturer, making tested replacement boards and professional PCB repair useful for maintaining existing FANUC robot equipment.

Because this PCB is associated with an emergency-stop system, the complete part number, connector arrangement, controller configuration, and original fault diagnosis should be confirmed before installation.
