FANUC A20B-1000-0850

Fanuc GRAPHIC board belongs to the system 10/11 model A. This color graphics PCB outputs to 14 inch CRT based color displays in Fanuc 10M/10T or 11M/11T CRT/MDI units. A20B-1000-0850 is a non surface mount main board which allows for a single display output. The GRP card interfaces with the CNC control via fibre optice link (F/O) and also offers secondary comms. As a result this board fits in the CRT/MDI with the display both powered by A20B-1001-0160 power supply unit.

We offer full 10 / 11 testing facilities whether its a graphics board issue with alarms such as a small c listing on the masterboard. The small c alarm is listed if the fault is caused on the PSU, graphics card or the F/O cable. Also comms problems can present if the GRP board is used in that capacity and lastly no display at all on the screen though the machine tool is otherwise fully functional. If you are unsure whether your A20B-1000-0850 is faulty then ship to us for testing. We have been repairing this board since the mid 90’s.  Repair is no problem and we also carry these boards in stock available for exchange.

As a rule we always try to keep these color GRP boards in our stocks. We carry fully refurbished A20B10000850 GRAPHIC cards. These are fixed by us where we have fully refurbished the printed circuit board replacing all the common components that fail on these cards as well the fault. These PCB’s are normally supplied on an exchange basis to save you money and time opposed to other non Fanuc specialist companies offering not much.
