Product Description

The ACG10S-F2121 S4 is a specialized communication gateway designed to bridge high-level industrial networks within the Yokogawa CENTUM control environment. It enables seamless Frame Mode and wide-area Ethernet communication, allowing integration of diverse fieldbus segments into a unified monitoring and control architecture. The “S4” revision represents an enhanced hardware version with improved stability and higher data throughput for complex automation systems.

This model supports dual-redundant V net (10BASE-5) communication, eliminating single points of failure and ensuring continuous data exchange in mission-critical applications. Its flexible design supports both 19-inch rack mounting and desktop installation, making it suitable for control rooms as well as localized system deployments.

Technical Specifications

Application Context

The ACG10S-F2121 S4 is widely used in large-scale industrial facilities such as:

• Refineries

• Upstream oil and gas operations

• Power generation plants

It enables “wide-area” communication by linking geographically separated control systems and connecting local V net networks to Ethernet-based supervisory and information systems. This ensures real-time data availability for higher-level analytics and control platforms.

FAQ

What does the “S4” revision mean?
The S4 designation indicates the fourth hardware revision, featuring improved internal components for better thermal performance and enhanced resistance to electromagnetic interference compared to earlier versions.

Does this unit support 220 V AC power?
No, the ACG10S-F2121 S4 is designed for 100–120 V AC input. For 220–240 V AC environments, a different model suffix must be selected to ensure proper operation and avoid damage to the internal power supply
