ABB Industrial Control Bus Integration

The TU847 3BSE022462R1 operates as a passive interface component within ABB System 800xA S800 I/O configurations. Therefore, it provides mechanical termination, power connection routing, and Modulebus termination functions for CI840 communication modules.

The unit supports ABB backplane bus communication structures where module positioning, connector alignment, and termination integrity affect I/O communication stability. Additionally, the included TB807 Modulebus Terminator completes the Modulebus connection path for non-redundant I/O installations.

The TU847 design follows ABB S800 I/O hardware architecture principles, allowing vertical installation of associated modules while maintaining the required electrical interface between the communication module and field I/O assemblies.

Frequently Asked Questions

Q: What ABB module is the TU847 3BSE022462R1 designed to support?
A: The TU847 is designed for CI840 communication interface installations and supports 1+1 CI840 configurations with non-redundant I/O operation.

Q: Does the TU847 include termination accessories?
A: Yes. The unit includes one Power Supply Connector and one TB807 Modulebus Terminator as specified in the product documentation.

Q: Is the TU847 a powered electronic I/O module?
A: No. The TU847 is a Module Termination Unit that provides physical termination and connection functions rather than performing signal processing.

Field Installation Guidelines

• Install the TU847 in the specified vertical mounting orientation within the ABB S800 I/O assembly.
• Verify that the CI840 interface module is correctly seated before applying system power.
• Confirm that the Power Supply Connector is properly installed and mechanically secured.
• Install the TB807 Modulebus Terminator according to the Modulebus termination requirements.
• Maintain separation between communication wiring and high-voltage power cables to reduce electrical interference.
• Connect grounding and shielding according to the control cabinet design and ABB installation requirements.
• Inspect connectors for contamination, mechanical damage, or improper engagement before commissioning.
