2105784-002 is an ABB display kit used with compatible 266-series pressure transmitter configurations. ABB identifies the part as an LCD display assembly with HMI connector, while its product description specifies the complete item as a button display assembly for 266XMV and 266HSH applications.
The kit combines the LCD display and HMI 6-pin connector into a replacement assembly, making 2105784-002 a field-replaceable component rather than a complete pressure transmitter. ABB lists it among the field replaceable parts for the 266 family.

| Associated Products | 266XMV, 266HSH |
| Application | Pressure transmitter display / HMI assembly |
What the Kit Contains
The 2105784-002 assembly is identified by ABB as a combined display replacement. The documented contents are:
- LCD display
- HMI 6-pin connector
This is important when matching the part against individual components. ABB separately lists ET3020 as an HMI 6-pin connector, while 2105784-002 is the display assembly that incorporates the LCD and HMI connector.
266 Series Compatibility
ABB's field-replaceable-parts documentation associates 2105784-002 with two product applications:
266HSH 4-20mA PT
and
266JST Modbus XMV
ABB lists the same part number under the LCD display assembly with HMI connector description for these configurations.
This makes the transmitter model an important matching reference when replacing the display assembly. The part should not be identified solely as a generic ABB LCD because the 266-series application is part of its product identity.

Position Within the 266 Replacement-Part Range
ABB's field-replaceable-parts list places several service components alongside 2105784-002, including:
| Part Number | ABB Description |
|---|---|
| 2105784-001 | Modbus Communication Assembly |
| 2105784-002 | LCD Display Assembly w/ HMI Connector |
| 2105784-003 | LCD Display, HMI 6-Pin Connector, Front Cover |
| AU3083 | Termination Assembly with Surge Protection |
| 214915 | Transmitter Back Cover |
| AU3067 | Termination Assembly with Surge Protection |
| AU3074 | HART Communication Assembly |
| ET3020 | HMI 6-Pin Connector |
These are separate field-replaceable items and should not be treated as interchangeable merely because they appear within the same ABB 266 parts list.
Replacement Identification
For maintenance and spare-parts matching, use 2105784-002 as the primary identifier. The associated descriptions "Display Kit" and "LCD display assembly w/ HMI Connector" can then be used to distinguish the item from other 266-series replacement parts.
Before replacing the assembly, verify the installed transmitter type. ABB specifically associates this part with the 266XMV / 266HSH display arrangement, so matching the transmitter family is preferable to selecting a display based only on physical appearance.
Application Reference
The 2105784-002 assembly is intended for the local display/HMI portion of compatible ABB 266-series pressure transmitter equipment. It is therefore relevant when the transmitter remains in service but the existing display assembly requires replacement.
ABB's documentation classifies these components as Field Replaceable Parts, which is consistent with using the complete 2105784-002 assembly as a maintenance replacement item.

FAQ
What is ABB 2105784-002?
2105784-002 is an ABB LCD display assembly with HMI connector for compatible 266-series pressure transmitter applications.
What does 2105784-002 include?
The documented assembly includes an LCD display and an HMI 6-pin connector.
Which ABB products use 2105784-002?
ABB's field-replaceable-parts documentation associates it with the 266HSH 4-20mA pressure transmitter and 266JST Modbus XMV.
Is 2105784-002 a complete pressure transmitter?
No. It is a replaceable display assembly for the compatible 266-series transmitter equipment.
Is the HMI connector included?
Yes. ABB identifies the item as an LCD display assembly with HMI connector, and the product description specifies an LCD display together with an HMI 6-pin connector.
Is ET3020 the same as 2105784-002?
No. ABB lists ET3020 separately as an HMI 6-pin connector, whereas 2105784-002 is the complete display assembly incorporating the LCD and HMI connector.
Is 2105784-002 a field-replaceable part?
Yes. ABB includes the part in its 266 Field Replaceable Parts documentation.
What should be checked before replacing this display kit?
Confirm the ABB part number 2105784-002 and the installed 266-series transmitter configuration, particularly whether the application corresponds to the documented 266XMV or 266HSH arrangement.
Procurement Reference
The complete ABB part number 2105784-002 should be retained when identifying this replacement assembly. For clearer matching, use the description Display Kit, 266XMV and 266HSH Button Display Assembly together with the part number.
This avoids confusion with 2105784-001, 2105784-003 and ET3020, which ABB lists as separate 266-series replacement components.
