Yokogawa S9564FA Hot-Swappable DCS Bus Connector

Product Overview

The Yokogawa S9564FA functions as a high-integrity bus connector unit specifically engineered for the CENTUM series Distributed Control Systems (DCS). This 100% Brand New original unit bridges the main control bus with field-side analog and digital modules, ensuring seamless data transmission and regulated 24 VDC power distribution. Its specialized T-shaped interface facilitates efficient signal branching, making it a cornerstone for scalable control architectures in the oil and gas, chemical, and power generation sectors.

Technical Specifications

Engineering Advantages

• Hot-Swappable Maintenance: The S9564FA features a true hot-swappable design. This allows maintenance teams to replace or upgrade modules without interrupting the system bus or initiating a costly process shutdown.

• T-Shaped Signal Branching: The unique T-interface architecture simplifies complex wiring layouts. It enables clean signal branching from the main backbone to individual I/O slots, reducing cable clutter and minimizing the potential for wiring errors during installation.

• Industrial-Grade Signal Stability: Yokogawa utilizes high-durability polymer housing combined with precision metal contacts to eliminate signal loss. This construction maintains stable electrical continuity even in environments prone to high-frequency vibration or thermal cycling.

• Wide Thermal Tolerance: The module operates reliably between –20°C and +70°C. This broad range ensures consistent performance in non-climate-controlled field cabinets or extreme industrial climates where standard commercial connectors fail.

• Dual Signal Support: This unit handles both digital and analog signal types simultaneously. This versatility allows engineers to mix and match I/O modules on the same bus segment, optimizing rack density and reducing overall hardware costs.

FAQs

• Q: Does the S9564FA require a specific mounting orientation?

• A: No. The S9564FA supports both rack and panel mounting configurations. Its compact 120mm profile fits standard Yokogawa DCS cabinet layouts, providing flexibility for tight control room enclosures.

• Q: How does the unit handle power distribution to the connected modules?

• A: The S9564FA manages a rated voltage of 24 VDC with a current capacity of up to 2 A per slot. This ensures that every connected analog or digital module receives a stable power supply for local logic and field-side sensing.

• Q: Is the IP20 rating sufficient for field deployment?

• A: The IP20 rating is designed for installation within a protected control cabinet or enclosure. For outdoor or extremely wet environments, you must house the S9564FA and its associated DCS rack in an appropriately rated NEMA or IP-certified secondary cabinet.

• Q: Can this connector unit replace older CENTUM bus interfaces?

• A: The S9564FA is specifically designed for modern CENTUM series digital bus architectures. We recommend verifying your specific backplane and CPU compatibility with our technical team before replacing legacy non-digital bus components.
