ALE111-S53 | Yokogawa | CENTUM Ethernet Communication Module

Product Overview

The Yokogawa ALE111-S53 functions as a specialized Ethernet interface module within the CENTUM control ecosystem. This module executes Modbus and DNP3 slave communication protocols, linking field control stations with external subsystems. It provides a reliable 10BASE-T physical layer connection via a standard RJ-45 port. We supply this unit as 100% Brand New and Original, ensuring full compatibility with your existing Yokogawa network infrastructure.

Part Number Breakdown

Technical Specifications

Engineering Advantages

• Native Protocol Support: The ALE111-S53 processes Modbus and DNP3 commands at the hardware level. This offloads communication overhead from the main controller CPU, maintaining high scan-rate performance in the control network.

• Standardized Physical Layer: The module utilizes a standard 100-ohm unshielded twisted-pair interface. This simplifies physical integration with standard Ethernet switches and hubs, removing the need for proprietary cabling.

• Versatile Compatibility: The module mounts directly onto SSC60, SSC50, SSC57, and SNB10D series hardware. Its compact 0.3 kg design allows for easy installation in high-density control cabinets where vertical space remains at a premium.

• Deterministic Throughput: By utilizing the CSMA/CD access method, the module manages bandwidth effectively in point-to-point connections, ensuring predictable packet delivery to external supervisory systems or HMIs.

FAQs

• Does this module support full-duplex Ethernet communication?

  No. The ALE111-S53 operates strictly on the IEEE 802.3 10BASE-T Half-duplex standard. Ensure your connected network switch or hub supports half-duplex auto-negotiation or manual port configuration.

• Can I use this module to connect to standard IT office networks?

  You can physically connect the module to standard networks; however, ensure the communication traffic remains restricted to the Industrial Automation protocols (Modbus/DNP3) to prevent packet collisions and network congestion.

• What is the maximum cable length between this module and the hub?

  The module supports a maximum segment length of 100 meters. If your architecture requires longer runs, you must install an intermediate Ethernet switch or repeater.

• Can the ALE111-S53 act as a Modbus Master?

  No, this specific model operates as a Modbus/DNP3 Slave. It responds to external requests; it does not initiate communication sequences to other slave devices.
