ABB 3BSE022462R1 TU847 MTU for CI840

Product Description

Configured for 1+1 CI840 non-redundant I/O execution within distributed control systems, the ABB 3BSE022462R1 (TU847 Module Termination Unit) provides direct physical and electrical execution for vertical module mounting. Furthermore, this hardware unit manages internal bus distribution and power delivery across the rack architecture, supporting continuous operation through integrated mechanical interfaces.

Hardware Specifications

Backplane Bus Communication Velocity and Racks

The ABB 3BSE022462R1 directly facilitates modulebus signal transmission via the included TB807 terminator, ensuring proper termination impedance for deterministic networks. Moreover, the backplane communication architecture maintains signal integrity across the vertical mounting profile. Consequently, the unit prevents reflection anomalies and preserves data exchange velocity between the CI840 controller interface and associated I/O modules. Technicians must verify proper seating of the modulebus connector to maintain uninterrupted telegram delivery during runtime operations.

Frequently Asked Questions

Q: Does the TU847 support live insertion and removal of connected I/O modules?

A: Yes, the mechanical design permits hot-swapping of field-side electronic modules while the base unit remains powered and mounted on the DIN rail, provided system-level software configurations allow it.

Q: What is the exact function of the included TB807 terminator?

A: The TB807 modulebus terminator provides the necessary characteristic impedance matching at the end of the internal serial communication bus, thereby eliminating signal degradation and communication dropouts.

Field Installation Guidelines

1. Mount the module vertically on a standard DIN rail within a grounded metallic enclosure, ensuring sufficient vertical clearance for heat dissipation and cable routing.
2. Secure the mechanical locking mechanisms firmly to prevent displacement caused by industrial vibration or thermal expansion.
3. Connect the primary power supply using the designated power supply connector included in the package, verifying correct voltage polarity before energizing the loop.
4. Attach the TB807 Modulebus Terminator to the final modulebus port on the termination unit to establish proper bus impedance.
5. Terminate all incoming field wiring securely to the respective terminal blocks while maintaining proper shielding and grounding practices to minimize electromagnetic interference.
