CP401-10 S1 Overview

The Yokogawa CP401-10 S1 Modules DCS CPU Module is a 24 VDC CPU Controller module. It forms the central node of the FFCS system, supporting up to eight I/O modules and enabling dual-redundant processor configurations for high system availability.

Application

• System Core: It serves as the primary CPU node in the FFCS control system.

• I/O Expansion: Supports connecting up to eight I/O modules for local signal processing.

• System Extension: Allows connection to a maximum of three additional extension nodes, including direct-coupling and remote nodes.

• Dual-Redundant Control: Enables high-availability system configurations using the Pair & Spare method.

• Fault Tolerance: Facilitates seamless control transfer during processor failure without system shutdown.

• Bus Integration: Uses ESB and ER bus interface modules (EC401/SB401/EB401) for node communication and expansion.
