Product Details

• Part Number 1 TU891

Product Description

Designed for the Advant 800xA platform, ABB TU891 is a Module Termination Unit.

Within the process-control arrangement, this type of unit concentrates field connections at a defined termination point before signals reach the related control-system electronics. Correct pairing with the associated I/O hardware is essential. Application should remain aligned with the documented system design.

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. Installation should follow the control node's approved hardware records.

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.
