Product Overview

The Yokogawa EC401-11 is an ESB bus coupler module, integral to the Yokogawa CENTUM VP system. This module provides the essential connection between the field control unit (FCU) and the ESB bus, facilitating high-speed and reliable communication. By linking the main controller with I/O modules on the ESB bus, the EC401-11 ensures seamless data transmission and system integrity. Built for demanding industrial environments, it ensures that the control system operates effectively and efficiently.

The EC401-11 is designed for redundant configurations, enhancing system availability and reliability. It features diagnostic LED indicators that visually represent the status and health of the bus and communication channels, simplifying maintenance and troubleshooting. The module’s compact design maximizes cabinet space, allowing for higher I/O module density in a single rack. The EC401-11 is a key building block for a robust, integrated control network.
