The ABB Bailey ITCTU05 is a multifunctional Communication Interface / Termination Unit Module used in the INFI 90 distributed control system (DCS). It acts as a critical communication gateway, enabling data exchange between the DCS core system and external devices, PLCs, SCADA systems, and industrial networks.
Unlike standard termination units, the ITCTU05 combines signal interfacing, protocol conversion, and communication routing, making it a powerful integration module for complex automation architectures. It is widely applied in power plants, oil & gas facilities, petrochemical industries, and large-scale industrial control systems, where multi-protocol communication is required.
