Product Description
The ABB Bailey NTCL01 is a Communication Termination Unit developed for use in the INFI 90® control system architecture. It serves as a physical interface between communication loops—either INFI-NET or Plant Loop—and key network modules such as the INNIS01 Network Interface Slave Module or the INLIM03 Loop Interface Module. Designed for installation on a Field Termination Panel (NFTP01), the NTCL01 provides support for both coaxial and twinaxial cables, with jumper-selectable impedance settings to ensure signal integrity.
As a robust and essential interface component, the NTCL01 ensures reliable data transfer across the network, offering flexibility in cable choice and ease of configuration. It also includes internal overcurrent protection via a fused +24 VDC input supply.
