Features:
- Legacy electronics identity: belongs to pre-2017 AT100/AT200 transmitters
- Generation boundary: differs mechanically and functionally from the 2017 module
- Serviceable module format: provides the local electronics and operator interface for the matched transmitter
M4A-AT is best identified as a legacy transmitter electronics assembly rather than the complete level instrument.
Its most important selection fact is the generation split introduced in 2017.
A visually similar later module must not be treated as a direct interchange without the matching transmitter architecture.
Apter Power can review M4A-AT face markings, transmitter generation, official enhancement records, condition, and quotation requirements.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Legacy marking: read the exact module part number on the installed face
- Transmitter build: determine whether the AT100/AT200 was produced before the 2017 change
- Board indicator: inspect the mounting area for the generation marker described by ABB
- Old-to-old pairing: use M4A-AT only with the applicable previous-generation transmitter
- New-to-new pairing: keep M4A-AT-2017 with the redesigned architecture
- Mixed generation: stop if module and mounting-board evidence disagree
- Photographic record: retain clear images of the module label and transmitter nameplate
- Configuration record: save the approved transmitter setup before electronics work
- Return test: compare the indicated level and output behavior with the process reference after service
- Legacy AT100 service: restore matched electronics in an installed magnetostrictive transmitter
- Legacy AT200 service: maintain the correct module generation during transmitter repair
- Spare identification: separate pre-2017 inventory from modules carrying the -2017 marking
