ABB Bailey NTCL01-A INFI-Net Communication Link Termination Unit

Product Overview

The ABB Bailey NTCL01-A is an INFI-Net Communication Link Termination Unit designed for the Bailey INFI 90 and Network 90 distributed control systems. It serves as the critical interface between INNIS01 (Network Interface Slave Module) or INLIM03 (Loop Interface Module) and the twinaxial or coaxial loop cables, providing reliable termination for INFI-NET® and Plant Loop communication networks. The NTCL01-A ensures signal integrity and prevents reflections in high-speed industrial communication loops.
