YOKOGAWA NFCP501/502 High Performance CPU Module for STARDOM FCN-500 Controller

Product Description

NFCP501 and NFCP502 are core processor modules of Yokogawa STARDOM FCN-500 field control node, responsible for real-time PID regulation, logic interlock, batch control and distributed I/O scheduling.

NFCP501: 2×Gigabit Ethernet ports, standard single/dual redundant CPU

NFCP502: 4×Gigabit Ethernet ports, support independent network isolation (control network + maintenance network)

Fanless low-power design with ECC error-correcting memory, supports CPU hot backup and online hot swap, compatible with CENTUM VP DCS, ProSafe-RS safety system and Modbus TCP/DNP3 third-party equipment, widely used in chemical, power and oil & gas distributed control cabinets as key maintenance spare parts.
