Yokogawa NFTCSS-00 Terminal Board

The Yokogawa NFTCSS-00, also cataloged as the NFTCSS Terminal Board, operates as a dedicated hardware component for field signal wiring and backplane I/O routing within Yokogawa CENTUM VP and CENTUM CS 3000 systems. Hardware Specifications Parameter Specification Model NFTCSS-00 Brand Yokogawa Origin Japan Weight 0.25 kg Dimensions Standard Yokogawa FIO terminal board format Operating Temp -20 to 55 deg C Power Consumption Passive hardware routing board Subsystem Compatibility Yokogawa FIO (Field I/O) System Compatibility CENTUM VP / CENTUM CS 3000 Wiring Method Heavy-duty screw-type terminals Relative Humidity 5 to 95% RH, non-condensing Channel-to-Channel Isolation and 4-20 mA HART Integration The Yokogawa NFTCSS-00 terminal board routes field signals through dedicated trace layouts with terminal-to-system isolation barriers, suppressing common-mode noise and preventing ground loops across sensitive measurement loops. Built for integration with paired FIO digital or analog sub-modules, the board supports transparent 4-20 mA HART loop protocol telemetry and FOUNDATION Fieldbus pass-through. Dedicated shield grounding terminals maintain continuous shield continuity from incoming field cabling directly to the I/O rack backplane, protecting signal paths against high-frequency electromagnetic interference (EMI). Frequently Asked Questions Q: Does the NFTCSS-00 require a specific torque limit for field terminal screw connections? A: Terminal screws should be torqued to standard industrial ratings (typically 0.5 to 0.6 Nm) to secure stripped wire leads or ring/spade lugs without damaging the threaded terminal blocks. Q: Can the NFTCSS-00 be used interchangeably with both analog and digital I/O sub-modules? A: Yes, the board serves as a universal pass-through interface card designed to mate with corresponding single or redundant FIO sub-modules on the baseplate assembly. Field Installation Guidelines Mount the terminal board firmly onto the designated Yokogawa I/O baseplate slot, ensuring the backplane multi-pin connector seats completely. Strip incoming field conductors and terminate them under the terminal screws, ensuring no stray wire strands extend outside the terminal barriers. Connect all field cable drain wires directly to the designated shield ground terminals on the board to establish low-impedance ground paths. Keep field wiring organized within panel channels, maintaining separation between high-voltage power lines and sensitive low-level analog signal leads. Verify cabinet environmental controls keep ambient operating temperatures between -20 and 55 deg C under full load conditions.
