S9564FA Yokogawa ESB Bus Connector Unit with Terminator

Product Overview

The Yokogawa S9564FA serves as the specialized Electronic Serial Bus (ESB) interface and termination module for the ANB10D Node Unit. This 100% Brand New unit facilitates high-speed communication between the Field Control Unit (FCU) and distributed I/O modules. By integrating a precision termination resistor, the S9564FA eliminates signal reflections that cause data corruption in complex bus architectures. It stabilizes the communication network within Yokogawa CENTUM VP and ProSafe-RS platforms, ensuring that critical process data reaches the controller without latency or distortion.

Technical Specifications

Engineering Advantages

• Signal Integrity Management: The S9564FA incorporates a high-precision internal terminator. This hardware-level termination matches the bus impedance perfectly, suppressing the "echo" effect of high-frequency pulses across long ESB cable runs.

• Streamlined System Topology: This unit combines the connection port and the terminator into a single chassis. This design reduces the number of separate components in the cabinet, simplifying the wiring layout and decreasing the risk of accidental disconnection or loose terminators.

• Industrial Noise Rejection: Yokogawa engineers the S9564FA to withstand the electromagnetic interference (EMI) prevalent in power plants and chemical refineries. The unit maintains clean data throughput even when situated near high-voltage switchgear or variable frequency drives.

• Versatile Power Architecture: The module supports various power configurations, including 24V DC for battery-backed systems and universal AC inputs. This flexibility allows global deployment across different regional power standards without requiring external transformers.

FAQs

• When must I use the S9564FA on an ANB10D node? You must install the S9564FA at the end of an ESB bus segment. The built-in terminator prevents the signal from reflecting back into the bus, which is mandatory for maintaining the high-speed data integrity required by CENTUM VP controllers.

• Does the S9564FA support the ProSafe-RS safety system? Yes. The S9564FA maintains full compatibility with both CENTUM VP (DCS) and ProSafe-RS (SIS) architectures, provided you utilize the ANB10D node unit.

• Can I hot-swap the S9564FA? Because the S9564FA acts as the bus terminator, removing it while the system is active will disrupt the ESB bus communication for all downstream modules. We recommend performing replacements during scheduled maintenance or following strict Yokogawa safety protocols for live systems.

• Is this a genuine Yokogawa product? Absolutely. We provide only 100% Brand New, original Yokogawa S9564FA units in their original factory packaging to guarantee compliance with your system's warranty and safety specifications.
