The ITCTU03/11 termination unit from ABB Bailey provides clean signal termination for INFI 90 and Net 90 field wiring. Technicians install this unit at the cabinet boundary to match field cables with controller I/O channels. Consequently, it reduces noise, reflections, and wiring errors in industrial control cabinets.

Functional Overview
This unit accepts field wiring and routes each signal to the correct controller channel. Therefore, it simplifies cable management during installation and retrofit projects. The ITCTU03/11 also houses termination resistors that prevent signal reflection on long runs. Meanwhile, its onboard energy storage stabilizes analog readings against transient electrical noise.
Installation and Handling Notes
Always strip field wires to the recommended length before inserting them. In addition, tighten each screw terminal to the specified torque value. Verify channel mapping against your loop drawings before powering the cabinet. Finally, label every terminal clearly for future maintenance work.
