FANUC A20B-8101-0191 Product Overview
The FANUC A20B-8101-0191 is an internal power supply PCB and DC-DC converter used in compatible FANUC Series 16i, 18i and 21i Model B CNC configurations. It is installed as a replaceable power-conversion section associated with the CNC main board.
This A20B number identifies the power module itself rather than the complete CNC control, main CPU board or external machine power supply. Exact replacement requires confirmation of both the installed board number and the host-control configuration.
Verified Power Board Identification
- Manufacturer: FANUC
- Part number: A20B-8101-0191
- Component type: Power supply PCB / DC-DC converter
- Board function: Internal CNC control power conversion
- Installation type: Replaceable bolt-on board attached to compatible main-board hardware
- Control context: Compatible 16i / 18i / 21i Model B configurations
Power Supply and Main Board Clarification
The A20B-8101-0191 supports the internal low-voltage power structure of the CNC control. It should not be confused with a servo-amplifier power module, spindle-drive power board or the complete main CPU assembly.
Some FANUC i-series controls use a separately replaceable power section, while other hardware versions integrate the power circuitry differently. A control-family name such as “16i” alone is therefore insufficient to confirm compatibility.
Replacement and Compatibility Guidance
Before ordering, compare the complete A20B-8101-0191 number, printed revision, connector layout, mounting points and host main-board number. Also confirm whether the original control is an integrated or stand-alone configuration.
This power board does not normally store CNC parameters or programs. However, a verified backup of machine data is recommended before servicing any CNC control. Disconnect power and allow the system to discharge before removal; installation should be completed by qualified personnel using suitable ESD precautions.
