ABB 68257867 AINT-02C

The ABB 68257867 AINT-02C is a main circuit interface board spare kit designed for compatible ABB ACS800 industrial drive systems. Its official designation is AINT-02C SP KIT MAIN INTERFACE; I/O KIT. The assembly serves as an interface within the drive's power-electronics and control architecture.

The AINT-02C is used in compatible drive configurations to support communication between the main circuit electronics and the drive control system. It is particularly relevant to maintenance and replacement of legacy ABB ACS800 equipment.

2. Technical Parameters

The exact drive compatibility depends on the drive model, frame size, hardware revision, and installed component configuration.

3. Product Features

Main circuit interface

The AINT-02C provides an interface between relevant drive electronics and the control architecture, supporting the coordinated operation of compatible ABB drive assemblies.

ACS800 system integration

The board is documented for use in the ABB ACS800 drive family, including specified single-drive configurations.

Fibre-optic communication

In documented ACS800 configurations, the AINT board connects to the RMIO motor-control and I/O board through a fibre-optic link.

Protective PCB coating

The coated circuit board provides an additional layer of protection for electronic components in suitable industrial operating environments.

Replacement and maintenance support

The 68257867 product ID provides a reference for sourcing the designated AINT-02C spare kit for existing installations.

4. Structural Composition

The ABB AINT-02C assembly comprises several functional elements:

1. Printed circuit board: Provides the mounting platform and electrical interconnections for the interface circuitry.

2. Interface electronics: Support signal exchange between the main circuit electronics and associated drive control hardware.

3. Signal-processing components: Support the board's designated interface functions.

4. Fibre-optic interface: Provides communication with the RMIO control board in applicable drive configurations.

5. Electrical connectors: Connect the board to the relevant internal drive assemblies.

6. Protective coating: Helps protect the circuit board against environmental contamination.

7. Mounting provisions: Secure the board within the designated drive assembly.

The detailed circuitry and connector layout depend on the board revision and drive configuration.

5. Application Fields

The ABB 68257867 AINT-02C is suitable for maintenance of compatible ABB drive installations in the following sectors:

• Industrial motor control: Supporting the internal electronics of compatible variable-frequency drives.

• Manufacturing automation: Maintaining drive systems used in production machinery.

• Pumping and water systems: Supporting compatible motor-drive installations.

• Fans and compressors: Maintaining drive electronics in industrial ventilation and compression equipment.

• Process industries: Supporting motor control systems in manufacturing and processing facilities.

• Legacy drive maintenance: Replacing a faulty main interface board in an existing ACS800 installation.

Actual suitability must be established from the original drive's component list and hardware configuration.

6. Conclusion

The ABB 68257867 AINT-02C is a coated main circuit interface board supplied as a spare kit for compatible ABB ACS800 drive systems. Its principal role is to provide interface functions within the drive's electronic control architecture.
