ABB NTCF22 Field Network Termination Unit

Product Description

The NTCF22 is a heavy-duty Module Termination Unit (MTU) engineered by ABB for legacy Bailey Infi 90 and modern Symphony Plus Distributed Control Systems (DCS). This vital hardware terminal block acts as the structural interface bridging complex processing modules with external field communication networks and peripheral data buses.

Industrial Application Scenarios

The NTCF22 communication termination unit is positioned inside the core marshalling panels of petrochemical refineries, thermal power plants, municipal water treatment systems, and heavy pulp mills relying on ABB Bailey control frames. In these large infrastructures, communication lines from remote multi-function processors must transition into physical plant networks. The NTCF22 serves as this secure connection point. Its integrated lead-acid batteries provide essential backup power to the localized network interface card, keeping communication nodes active during blackouts so the central control room can track diagnostic statuses and safety interlocks as the plant undergoes emergency sorting cycles.
