Yokogawa SSB401-S53 Bus Interface Slave Module

Product Introduction

The Yokogawa SSB401-S53 is an ESB Bus Interface Slave Module designed to bridge field devices and sensors with a central Distributed Control System (DCS) via Yokogawa’s Ethernet-based Standard Bus (ESB) protocol. Engineered for robust, high-precision communication, it ensures seamless integration into both new and existing Yokogawa automation installations.

Technical Parameters

Applications

• Integration of analog and digital field signals into Yokogawa DCS networks for process control and monitoring

• Extension of safety-instrumented loops within ProSafe-RS or CENTUM systems via ESB

• Data aggregation from remote I/O racks and substations in utilities, chemical plants, and oil & gas installations

Key Advantages

1. High Precision & Stability: ±0.05 % full-scale accuracy minimizes calibration drift and ensures repeatable readings.

2. Multi-Protocol Flexibility: Supports leading industrial networks (PROFIBUS DP, DeviceNet, CANopen) alongside proprietary ESB.

3. Compact & Robust: Small footprint (150 × 20 × 25 mm) and rugged –10 °C to +60 °C operation.

4. Seamless DCS Integration: Plug-and-play with Yokogawa’s CENTUM VP/CS 3000 and ProSafe-RS systems over Vnet/IP.

5. Easy Configuration & Diagnostics: Built-in monitoring tools accelerate commissioning and reduce downtime.

Frequently Asked Questions (FAQ)

1. What is the primary purpose of the SSB401-S53?
   It acts as a slave interface, converting diverse field signals into standardized ESB data streams for Yokogawa DCS.

2. Which signals can I connect?
   Voltage, current, thermocouples, RTDs, and digital I/O types.

3. How do I power the module?
   It requires a 24 V DC supply, with typical consumption below 0.5 A.

4. Can I mix protocols on one ESB network?
   Yes—depending on firmware, it supports ESB, PROFIBUS DP, DeviceNet, and CANopen.

5. What is the maximum network length?
   Network length follows ESB specifications; use repeaters (e.g., SNT411/SNT511) for distances >100 m.

6. How is configuration performed?
   Via Yokogawa’s engineering software (ENG) over Vnet/IP; no DIP-switches required.

7. What maintenance is needed?
   Periodic verification of signal accuracy and firmware updates; no moving parts.

8. Is it SIL-rated for safety loops?
   Yes—when used with ProSafe-RS hardware, it supports SIL 3 applications.

9. What’s the ambient temperature range?
   –10 °C to +60 °C, suitable for most plant environments.

10. How do I diagnose communication issues?
    Use built-in LED indicators and software diagnostics in Yokogawa’s DCS suite.
