Product Details

  • Part Number 1 TU921B

Product Description

TU921B is identified by ABB as a Redundant Termination Unit within the Advant 800xA family.

For replacement planning, 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 original equipment schedule should guide compatibility review.

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. The plant's maintenance records should support final product selection.

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. Ratings and capacity should be verified against the exact model documentation.
