• Suffix Code -410:

• 4: Dual-redundant power supply

• 1: 100-120 V AC power supply

• 0: Basic type

• Mounting: 19-inch rack mountable

• Communication: Dual ESB bus interface

• Power Consumption: Approximately 100 VA

• Weight: Approximately 10 kg (fully loaded with power supply units)

Key Features

• High Reliability: Supports dual-redundant power supplies and communication cables to prevent system downtime in case of a single point of failure.

• Seamless Integration: Designed specifically for Yokogawa’s proprietary RIO (Remote I/O) and FIO (Field I/O) architectures.

• Hot-Swappable: Supports the replacement of interface modules without interrupting the operation of the remaining system.

• Condition Monitoring: Built-in diagnostics provide real-time status updates on power supply health and bus communication quality.

Application and Usage

This unit is typically installed in cabinet assemblies where high-density I/O processing is required. It is commonly used in:

• Oil & Gas Refineries: Managing large-scale sensor arrays.

• Chemical Processing: Handling complex control loops with high redundancy requirements.

• Power Plants: Ensuring stable communication between distributed control nodes and the central station.
