Yokogawa F3BU20-0N FA-M3 Main Base Module

Product Overview

The Yokogawa F3BU20-0N functions as the high-capacity structural foundation for the FA-M3 "Range-free" multi-controller system. This main base module provides 20 dedicated slots for power supply, CPU, and various I/O modules, enabling large-scale automation architectures. We supply this unit as 100% Brand New and Original, ensuring absolute bus integrity and mechanical precision for your complex control infrastructure.

Technical Specifications

Engineering Advantages

• Ultra-High Slot Density: The 20-slot design of the F3BU20-0N eliminates the need for multiple smaller bases in complex applications. This consolidation reduces cabinet footprint and simplifies the internal communication bus, streamlining the overall system architecture.

• Stable Signal Propagation: The high-integrity backplane minimizes signal crosstalk and ensures deterministic data transfer between the CPU and remote I/O modules. This stability remains critical for high-speed motion control and synchronized process tasks.

• Industrial-Grade Resilience: Yokogawa engineers this base to operate within a wide temperature range (up to 55°C). The fan-less, passive design prevents dust accumulation on critical bus connectors, extending the Mean Time Between Failures (MTBF) in harsh factory environments.

• Simplified Installation Logic: The unit features standardized M4 mounting holes for secure panel installation. This mechanical rigidity protects the module pins from the vibration and shock commonly encountered in heavy industrial machinery.

FAQs

• Which power supply modules work with the F3BU20-0N?

  The F3BU20-0N supports standard FA-M3 power supply modules such as the F3PU20 or F3PU30 series. Always verify that your power supply current rating (e.g., 4.3A or 6.0A) matches the total consumption of the CPUs and I/O modules installed on the base.

• Can I use this base for expansion sub-units?

  The F3BU20-0N primarily functions as a main base unit. For expansion, you typically connect sub-units via the FA-bus. Ensure your CPU module supports the total number of points and bases in your planned configuration.

• Does the 20-slot count include the power supply and CPU slots?

  Yes. In the FA-M3 architecture, the slot count refers to the total available positions on the backplane. You must reserve the dedicated positions for the power supply and at least one CPU module when planning your I/O layout.

• What are the environmental restrictions for this base module?

  Maintain an atmosphere free of corrosive or flammable gases. While the module handles humidity up to 90% RH (non-condensing), heavy dust or metallic particles can interfere with the backplane connectors; therefore, we recommend using an enclosure with a minimum IP54 rating in such conditions.
