What's the part number for my Milnor Circuit Board?

Many times our customers call requesting part number information for their Milnor Circuit Board.  Be it a processor board, input/output board, display board or other types, our customers are often surprised to find that the part number was right in their hands. 
With very few exceptions, all of the Milnor Circuit boards are labeled with their part number.  Some examples of the exceptions are shown at the bottom of the page.
The following pictures are of various circuit boards that pinpoint where the part number information is located.  The part number label will be outlined in red with an arrow pointing to the larger picture of the label. 

Processor Boards

Display Boards

Note the labels outlined in yellow.  These labels denote the software version on the chip, not to be confused with the part number of the board. 
Software Chip labels will start with the letters WU.  When ordering software you need the WU number and the digits that are printed under the number.  

Power Supply Boards

 



Analog to Digital Converter Boards

Input Output Boards

Start Circuit Boards

Exceptions to the Rule

For various reasons some boards don't have the part number on them.
The board below is a Snubber Board. Though it has no tag, it does have a etched part number on the board.  



The part number etched on the board is 08BNCMBB.  The "B" indicates the "bare" board part number   In most cases the part number to purchase replaces the "B" with a "T".  

A tested circuit board will almost always end with the letter 'T'.  Exceptions exist for some boards on import models. 
The 98CMCR1823 Display Board is shown below.



The 98CMCR1825 Power Supply is shown below.
The fuse on this power supply is 4A 250VAC.


There is no label on this Power Supply Board showing the part number. The part number for all boards can be found in the schematic page for electrical components.  

Always start with a look at the circuit board you want to replace.  For the most part, the part number will probably be right in your hands.
