Detailed Product Overview
The ABB D674A906U01 is a plug-in electronics cartridge that forms the core of the transmitter electronics in ABB’s FET300 series electromagnetic flowmeters. The FET300 platform (ProcessMaster and HygienicMaster) uses a common cartridge design across both compact (integral) and remote transmitter housings. This standardization reduces the number of distinct spare parts required for maintenance.
The cartridge provides the HART communication interface that allows online parameter modification, monitoring, and diagnostics from a HART handheld communicator or asset-management system. The “U-high” designation identifies the specific hardware variant of the cartridge intended for the standard HART configuration of the FET300 transmitter.
Because the same cartridge type is used in both integral and remote installations, a single spare can support multiple transmitter styles within the ProcessMaster/HygienicMaster family. The module is supplied as a new spare part and is intended for direct replacement of the existing electronics cartridge inside the transmitter housing.
Installation requires isolation of the transmitter power supply before the cartridge is removed or inserted. After replacement, system data and configuration must be restored according to the flowmeter operating instructions. The cartridge itself contains no field wiring terminals; all process and power connections remain on the transmitter backplane or terminal board.
System Compatibility & Integration Requirements
| Item / Dependency | Verified Compatibility or Requirement | Practical Note |
|---|---|---|
| Transmitter family | ABB | ProcessMaster and HygienicMaster electromagnetic flowmeters |
| Communication protocol | HART (standard) | Online configuration and diagnostics via HART |
| Mounting style | Integral or remote transmitter | Same cartridge used in both configurations |
| Replacement procedure | Power isolated before insertion/removal | Restore configuration data after installation |
| Product role | Spare electronics cartridge | Direct plug-in replacement for existing FET300 cartridge |
Dimensions, Mounting & Connection Notes
The D674A906U01 is a compact plug-in electronics cartridge with a net weight of 0.25 kg. It is installed inside the transmitter housing of the FET300 series. No additional field wiring is attached directly to the cartridge; connections are made through the transmitter backplane or terminal board. Power must be isolated before the cartridge is removed or fitted.

FAQ
What is the ABB D674A906U01?
It is the Cartridge U-high HART / Std. electronics module used as a spare part in ABB FET300 series electromagnetic flowmeter transmitters.
Which flowmeters does it support?
It is compatible with ProcessMaster FEP3xx, HygienicMaster FEH3xx, and FET3xx transmitters in the FET300 family.
What communication protocol does it provide?
It supports the standard HART protocol for configuration, monitoring, and diagnostics.
Can the same cartridge be used in both integral and remote transmitters?
Yes. The FET300 platform uses a common electronics cartridge for both integral-mount and remote-mount installations.
Is this a complete transmitter or only a sub-assembly?
It is the replaceable electronics cartridge (spare part) that fits inside the transmitter housing; it is not a complete transmitter unit.
What is the weight of the cartridge?
Net weight is 0.25 kg.
Where is the part manufactured?
Germany.
Verification & Troubleshooting Notes
- Confirm the transmitter is a FET300 series unit (ProcessMaster or HygienicMaster) before ordering.
- Isolate transmitter power before removing or inserting the cartridge.
- After replacement, reload system data and verify HART communication and configuration parameters according to the flowmeter operating instructions.
- Ensure the cartridge variant (U-high HART / Std.) matches the existing transmitter electronics type.
