YOKOGAWA NFBU200-S Base Unit

Configured for interconnecting CPU, communication, and I/O modules in CENTUM VP platforms, the YOKOGAWA NFBU200-S (NFBU200 Base Unit) provides direct physical/electrical execution. The rack-mounted backplane unit routes power and system signals across an internal ESB backplane bus to execute real-time control operations.

Process Control & DCS Backplane Interfacing

The base unit distributes continuous logic power and high-speed communication signals to attached field control components. Integrated isolated bus pathways maintain signal fidelity across connected 4-20 mA HART loop protocol interface cards and digital I/O nodes. The physical traces resist cross-talk noise and prevent ground potential shifts between field loops and internal processor modules.

Frequently Asked Questions

Q: How does the base unit backplane handle module replacement during active process operations?

A: The backplane architecture supports online hot-swapping, allowing technicians to replace installed I/O or communication cards without interrupting power to adjacent slots or shutting down the active Field Control Station.

Q: What cooling provisions are necessary when populating all available module slots?

A: The unit operates via natural convection under standard ambient conditions up to 40 deg C; however, forced fan ventilation inside the enclosure is required when ambient temperatures range between 40 and 55 deg C.

Q: Can the base unit accommodate redundant power supply modules?

A: Yes, the chassis features dual power input terminals and dedicated backplane bus traces to accept redundant 24 VDC power supply modules for fault-tolerant execution.

Field Installation Guidelines

Mount the base unit horizontally inside a standard 19-inch equipment rack using four M6 panel screws. Secure the ground earth terminal directly to the enclosure grounding bar using a low-impedance copper strap to establish proper protective earth continuity.

Maintain a minimum clearance of 50 mm above and below the chassis to permit unimpeded air circulation. Route incoming 24 VDC power lines and ESB bus communication cables through dedicated, shielded wire channels, maintaining at least 300 mm separation from high-voltage AC conductors.
