Product Description

The ALE111-S50 (S1) is a high-performance Ethernet communication interface designed for the Yokogawa Electric Corporation CENTUM VP and legacy CENTUM CS 3000 / CENTUM CS 1000 control architectures.

This module functions as a subsystem communication gateway, allowing the DCS to exchange process and diagnostic data with external intelligent devices such as:

• PLC controllers

• Gas chromatographs

• Intelligent electronic devices (IEDs)

• Third-party automation subsystems

The ALE111-S50 S1 is a standard Ethernet communication variant, designed for high-speed data exchange, low latency control messaging, and stable 24/7 operation in general industrial environments. It occupies a single FCS I/O slot and is optimized for low power consumption with efficient thermal dissipation.

Detailed Technical Specifications

Suffix Code Meaning

• S — Standard hardware type

• 5 — Non-explosion-proof specification

• 0 — Basic functional configuration

Industrial Application Scenarios

The ALE111-S50 S1 is widely used in plant-wide integration architectures where the DCS must communicate with external automation systems. Typical applications include:

• Power generation monitoring systems

• Water and wastewater treatment automation

• Food and beverage process control

• Laboratory and analytical instrumentation integration

The module is especially suitable for data acquisition and supervisory communication tasks, enabling Yokogawa DCS systems to act as central supervisory controllers across heterogeneous automation networks.

Frequently Asked Questions

Does the ALE111-S50 S1 support redundancy?
Yes. The module can be installed in redundant pairs within compatible racks to ensure communication continuity. If one module fails, the backup module maintains network connectivity.

Can this module be used in hazardous areas?
No. The “5” suffix indicates non-explosion-protected hardware. Installation should be limited to safe areas or protective enclosures compliant with facility hazardous zone classifications.

What communication protocols are supported?
The module supports standard Ethernet-based communication protocols such as TCP/IP and UDP for subsystem integration and data exchange.
