Overview

The SE4101 Ethernet I/O Card (EIOC) is a high-performance communication interface within Emerson’s DeltaV DCS. It enables direct integration of Ethernet-based devices—including PLCs, motor control centers, drives, and intelligent field devices—without the need for intermediate controllers. This reduces system complexity, enhances scalability, and improves overall performance.

The card supports redundant configurations, ensuring high availability in mission-critical applications. It also allows control modules to be assigned and executed directly in the EIOC, providing flexibility and efficiency in distributed control architectures.

Technical Specifications

Typical Applications

• Process Automation: Connects smart devices such as analyzers, drives, and MCCs directly to DeltaV.

• Power Generation: Interfaces with IEC 61850-enabled switchgear and protection relays.

• Oil & Gas: Provides reliable communication with drilling and pipeline equipment.

• Manufacturing: Integrates PLCs and intelligent devices into a unified DeltaV system.

• Utilities: Supports Ethernet-based device connectivity in water treatment and distribution systems.

Example:
In a power plant, the SE4101 connects IEC 61850 relays and switchgear directly to DeltaV, eliminating third-party gateways and ensuring faster, more reliable communication.
