GE Mark VI and Mark VIe Part Number Explanation

When dealing with legacy systems, it is critical to understand component number naming conventions and how these part numbers have changed over time. XingRuiDa Automation offers many legacy systems, including the Speedtronic Mark I-II, Mark IV, Mark V, and Speedtronic Mark VI and Mark VIe series boards.

We can use GE’s Speedtronic Mark VI and Mark VIe as an example to show how this works. They have established part numbers to provide the user with a great deal of information – if you know how to interpret it correctly. Consider the following scenario, using the IS200AEAAH1CPR1 board as an example, where we can divide the number into components, each of which tells us something about the board: is/2/00/aeaa/h/1/c/pr1
