More Information

Overview Manuals Specifications Module Matching Spring Wiring 24 V Review

Features:

  • I/O application: Supports the documented group of digital and analog I/O modules.
  • 24 V DC class: ABB lists TU516 for 24 V DC terminal-unit applications.
  • Spring terminals: The field side uses spring connections rather than screws.

TU516 combines the mechanical I/O base and spring-terminal field connection for supported AC500 S500 modules.

Replacement work should record plug-in module identity, terminal numbers, supply groups, commons, shields, conductor treatment, and cabinet position.

Ordering review should distinguish TU516 from TU516-H and verify 1SAP212000R0001 against the installed label and compatibility matrix.

Availability is subject to Apter Power's current inventory and sourcing confirmation.

Compatible I/O review

  • Module group: Use TU516 with the digital and analog modules documented by ABB.
  • Hot-swap variant: Do not confuse standard TU516 with TU516-H.
  • Relay boundary: Relay-output modules are assigned to TU531 or TU532.
  • Order codes: Record both the terminal unit and installed I/O module.

Conductor termination review

  • Connection type: TU516 uses spring terminals on the field side.
  • Conductor record: Preserve channel numbers, supply groups, commons, and shields.
  • Preparation: Apply the approved stripping length and ferrule practice.
  • Retention check: Inspect each conductor after insertion and before power is restored.

Supply restoration checks

  • Voltage class: Confirm the terminal-unit application is 24 V DC.
  • Power groups: Rebuild only the documented potential distribution.
  • Safe isolation: De-energize the field circuits under the approved procedure.
  • Channel test: Commission each input and output against the verified I/O schedule.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What is ABB TU516 used for?
It connects field wiring to supported AC500 digital and analog I/O modules through spring terminals. Verify the module pairing before purchase.
How is TU516 different from TU515?
ABB lists TU516 with spring terminals and TU515 with screw terminals. The exact order code and wiring preference must be confirmed.
How can I verify the correct TU516?
Match TU516 and 1SAP212000R0001 on the terminal unit, quotation, and official ordering data, then check the I/O compatibility matrix.
Is TU516 the same as TU516-H?
No. They have different order codes and the H version is identified for hot-swap use. Do not interchange them without official confirmation.
Is TU516 active or discontinued?
ABB identifies TU516 as Active in the reviewed product information. Apter Power must still confirm current availability.
Does ABB list a replacement for TU516?
No replacement is identified in the reviewed sources. A different terminal unit needs separate fit, voltage, and wiring review.
How do I request TU516 price and lead time?
Open the verified Manuals resource and send Apter Power the exact module pair, quantity, condition, destination, and schedule.
