Product Description

The product identified as ABB TU843 is a Termination Unit in the Advant 800xA hardware family.

Within the process-control arrangement, termination hardware provides the organized transition between field wiring and associated I/O electronics. It supports installation, testing, and maintenance by keeping external connections aligned with the intended module interface. Final selection should be based on the plant's controlled-equipment records.

ABB Advant and System 800xA environments combine control, I/O, communication, and operator resources. This product supports the hardware function identified by its description within the installed system. This helps preserve the function assigned to the installed control node.

For ongoing lifecycle support, proper application depends on matching the product to the original control-system design, including its physical position, electrical connections, and configured relationship with surrounding hardware. Application details remain governed by the exact product revision.
