Product Description

Within the Advant 800xA product line, ABB TU840 serves as a Termination Unit.

From a maintenance perspective, 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. The product remains part of the broader control and signal-handling arrangement.

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. Connection and configuration should follow the requirements of the platform.

When this product is used for lifecycle support, technicians should confirm the installed revision, connection arrangement, and system assignment rather than assuming interchangeability with a similarly named module. The surrounding rack and module arrangement should be reviewed before installation.
