Industrial Overview
The ABB Bailey NTCL01 Control I/O Termination Unit is a core interface component used in the INFI 90 / Network 90 Distributed Control System (DCS). It is designed to provide a stable and reliable termination point between field wiring and system communication modules, ensuring accurate signal transfer and robust network performance in industrial automation environments.
This unit is primarily used to interface Network Interface Slave Modules (INNIS01) and Loop Interface Modules (INLIM03) with the INFI-NET communication architecture. It supports both coaxial and twinaxial cabling options, making it a flexible solution for complex plant communication networks operating under harsh industrial conditions.
