System Architecture & Signal Flow
In a CENTUM VP architecture, field instruments (transmitters, actuators, switches) connect via multi-pair cables to marshalling cabinets. The NNFTA4S-00-S2 terminal block module serves as the structured termination point within these cabinets, providing individual screw terminals for each field signal pair. Signals are then routed via system cables to the corresponding CENTUM VP I/O cards housed in the field control station (FCS). This module sits at the critical boundary between the field wiring domain and the DCS I/O domain, making its reliability and correct specification essential to overall system performance.
