Product Overview
The ABB Bailey ITCTU04 Terminal Unit is a field termination and interface module for ABB INFI 90 / Network 90 distributed control systems (DCS). It provides a centralized point for connecting field devices to the DCS, allowing organized, safe, and reliable wiring of digital and analog signals.
The ITCTU04 is similar in purpose to the ITCTU03 series but designed to handle higher signal density or enhanced power handling, as reflected in its higher weight compared to ITCTU03 models.
