This DL ADMM R04 accessory module prototype is an initial concept proof for end-to-end system integration, deployed for initial system proofing circa 10 years ago (as of this writing), meeting an end-user program requirement. A Rev 05 and New Model for 2026 deployment are in development now.
It’s functionality depends heavily on how the board is populated, ie, its “assembly variant” aka “AV”.
There are 2 assembly variants in discussion in this post, as examples. Many assembly variants are possible. Let’s call them:
- Legacy standard (“LS”) or (“AV-LS”)
- Heavy filtering in ATTEN mode for “DC” potentials. The quotation marks around “DC” are on purpose and very important.
- 2024 UNFILT ATTEN or NO FILT ATTEN (“NFA”) or (“AV-NFA”)
- For monitoring and characterizing high voltage AC potentials.
Functionality of the system implementation, including measurement specifications, also depends heavily upon:
- DL firmware (DL FW) and then of course
- RMU and field integration and electronics as well as
- Server-side data consumption, digestion – aka back end – and
- Server presentation – aka front end.
Why the * in the Title?
AC can mean many things; same for DC. Each measurement mode or configuration may, by design, implement different band pass characteristics. On purpose. That is, some measurement modes may allow higher frequencies into the measurement output, while some may allow only lower frequencies, or very very low frequencies aka DC.
AC: AV-LS vs AV-NFA
