ABB’s current product record gives the catalog description “Cartridge U-high HART / Std. FET 300” and a net product weight of 0.25 kg. The ABB spare-parts documentation specifically separates this 230 V cartridge from the 24 V D674A905U01 version.
Product Introduction
The ABB D674A906U01 is a plug-in electronics cartridge used in compatible ABB FET300 electromagnetic flowmeter transmitter assemblies. Its documented configuration is the 230 V HART standard version, intended for ProcessMaster and HygienicMaster equipment where the FET300 transmitter electronics require this specific cartridge arrangement.
This part should be treated as a transmitter electronics spare, not as a complete flowmeter or a generic analog/HART interface card. The distinction matters during replacement: sensor type, transmitter family, supply configuration, hardware index, and installed electronics architecture all need to match the original instrument.

Engineering Pain Point
The main replacement risk with D674A906U01 is confusing the cartridge with a complete transmitter assembly. ABB’s spare-parts documentation places it specifically under the FET301 transmitter plug-in module and identifies separate 24 V and 230 V variants. Installing the wrong supply version can turn an apparently correct mechanical replacement into an electrical incompatibility.
Typical Applications
- ProcessMaster electromagnetic flowmeters — replacement transmitter electronics for compatible FET300 configurations.
- HygienicMaster electromagnetic flowmeters — used where the installed transmitter architecture calls for the standard HART cartridge.
- Plant flow measurement loops — supports integration of the flowmeter transmitter with a control system through its documented HART-capable configuration.
- Instrument maintenance — suitable as a cartridge-level spare when the existing FET300 transmitter hardware is otherwise serviceable.
Technical Pitfalls to Avoid
- Do not confuse the 230 V and 24 V versions.
ABB identifies D674A906U01 as the 230 V HART standard cartridge, while D674A905U01 is the corresponding 24 V HART standard version. They should not be selected interchangeably. - Verify the transmitter hardware index.
ABB’s spare-parts documentation explicitly organizes these cartridges by hardware index. The installed /FET301 revision should therefore be checked before approving a replacement. - Do not use generic flowmeter specifications from unrelated sources.
Claims such as a particular flow range, ±0.5% measurement accuracy, IP67 rating, or Modbus/PROFIBUS capability should not automatically be attributed to this cartridge. Those characteristics belong to particular complete transmitter/sensor configurations, not necessarily to the itself. - Check the original cartridge identification.
Earlier ABB references include D674A881U01 and D674A900U01, both of which are documented as replaced by in the applicable spare-parts documentation. - Preserve transmitter configuration.
Replacing the cartridge does not eliminate the need to verify sensor calibration data, flow direction, measuring range, output configuration, HART settings, and other transmitter parameters. - Do not mistake the part for a standalone PLC/DCS module.
The belongs inside the ABB flowmeter transmitter architecture. Its compatibility depends on the complete instrument assembly.

Procurement Note
For a replacement, specify the complete part number and verify the existing transmitter’s /FET301 family, 230 V supply configuration, hardware index, HART configuration, and original cartridge marking.
The most important distinction is simple: is a 230 V HART-standard transmitter cartridge, not a complete flowmeter transmitter. ABB’s own spare-parts documentation supports this identification and records as the recommended spare for the applicable configuration.
