Features:

  • Provides a common mechanical and electrical platform for controller modules.
  • Supports both 19-inch rack and DIN-rail installation.
  • Withstands demanding industrial vibration, shock, electromagnetic, and environmental conditions.
Reliable controller construction begins with a stable platform for every processing, power, and signal interface component. Yokogawa NFBU200-S10 S1 gives FCN-500 hardware a unified mounting arrangement inside cabinets and instrument panels. CPU, power supply, and I/O modules can be assembled as one coordinated control unit. The base structure helps maintain orderly module positioning and internal communication. Industrial facilities can use the arrangement for standalone STARDOM control or CENTUM VP subsystem integration.

Mechanical installation flexibility allows Yokogawa NFBU200-S10 S1 to fit different panel-building practices. A 19-inch rack configuration supports conventional cabinet layouts, while DIN-rail mounting suits compact control enclosures. Insulation bushings help preserve electrical separation when the module is secured to a rack or general-purpose panel. Rear DIN-rail attachments provide a direct hook-and-push installation method. Natural air cooling further simplifies cabinet design by avoiding a dedicated module fan.

Grounding and environmental control remain important for dependable FCN-500 operation. Yokogawa NFBU200-S10 S1 must be grounded separately from motor-control circuits, electrical-control circuits, and unrelated equipment. The FG, protective ground, and line-filter ground connections must follow local electrical standards. Single-point grounding between the base module and power supply module helps maintain the required grounding arrangement. Proper installation supports stable operation in automation systems exposed to vibration, shock, electrostatic discharge, electromagnetic fields, and changing industrial temperatures.

The NFBU200-S10 S1 Yokogawa Base Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Serving as the mechanical backbone and electrical bridge of an FCN-500 controller, Yokogawa NFBU200-S10 S1 supports the installation and interconnection of CPU modules, power supply modules, and various I/O modules. Installed components use the base module to operate together and exchange system information. The assembly can function as part of a STARDOM autonomous controller or as a subsystem integrated into a CENTUM VP distributed control system. Such a structure supports organized controller construction in industrial automation cabinets and instrument panels.

Environmental specifications allow Yokogawa NFBU200-S10 S1 to operate from -20°C to +70°C and withstand transportation temperatures from -40°C to +85°C. Permitted ambient humidity ranges from 5% to 95% RH without condensation. Ambient temperature fluctuation must remain within ±10°C per hour during operation and ±20°C per hour during transportation. The specified dust concentration is 0.3 mg/m³ or less, the protection class is IP20, and the maximum installation altitude is 2000 m.

Industrial environmental resistance for Yokogawa NFBU200-S10 S1 includes ANSI/ISA S71.04 Class G2 corrosive-gas resistance as standard, with Class G3 available as an option. Vibration resistance is rated at 0.15 mm peak-to-peak from 5 to 58 Hz and 1 G from 58 to 150 Hz. Shock resistance reaches 15 G for 11 ms during power-off, based on sine half-waves applied in the X, Y, and Z directions. The permitted electric field is 3 V/m or less from 26 MHz to 1 GHz, while magnetic-field limits are 30 A/m or less for AC and 400 A/m or less for DC. Electrostatic-discharge resistance is specified at 4 kV or less for contact discharge and 8 kV or less for air discharge.

Natural air cooling supports fan-free operation of Yokogawa NFBU200-S10 S1, while installation options include a 19-inch rack and a DIN rail. Rack or general-purpose control-panel installation requires the supplied insulation bushings to be placed around the base module before fastening with the supplied screws. DIN-rail installation uses the rear attachments by hooking the upper tab onto the rail and pushing the base module into position. FCN-500 grounding must remain separate from other devices, motor-control circuits, and electrical-control circuits. The FG terminal, protective grounding terminal, and power supply module G terminal must be grounded according to applicable regional standards, with the base module and power supply module connected to ground at one point.
