IC660BBD, IC660EBD and IC660TBD – Can’t We All Just Get Along?

Digital Genius Blocks from GE are made up of 2 components – the electronic assembly (IC660BBD) and the terminal assembly (IC660TBD).  These components make up the Genius block – IC660BBD part number.  Here is a table of all combinations:

IC660BBD020 IC660EBD020 IC660TBD020
IC660BBD021 IC660EBD021 IC660TBD021
IC660BBD022 IC660EBD022 IC660TBD022
IC660BBD023 IC660EBD023 IC660TBD023
IC660BBD024 IC660EBD024 IC660TBD024
IC660BBD025 IC660EBD025 IC660TBD025
IC660BBD101 IC660EBD101 IC660TBD101
IC660BBD110 IC660EBD110 IC660TBD110
IC660BBD120 IC660EBD120 IC660TBD120
 If you look at the Genius block itself, you will see the above part numbers in the proper combination and these part numbers will end with a letter or a revision letter (like IC660BBD101F).  Typically, the revision letter of both the EBD and the TBD part numbers is the same.  But there is a caveat to that thinking.

If you have a Genius block that has the letter A, B, C, D or E at the end, then both the EBD and TBD must have the same letter at the end (these are know as Phase B, Generation One Genius Blocks).
However, if the ending letter is F or higher, then you can mix and match and revision of the EBD and TBD part, provided they are both F or better.

If you have newer terminal strips that are version F or higher but old electronics, we can upgrade the firmware in the EBD electronics section so they will compatible with the higher TBD version.
