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.

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.
