The YOKOGAWA SPW482-13, also cataloged as the SPW482-13 Power Supply Module, operates as a dedicated hardware component for power distribution within CENTUM VP and related process control platforms.

Hardware Specifications

Process Control Power Stabilization

The SPW482-13 is a specialized power supply module engineered exclusively for the Field Control Unit (FCU), FIO Node Unit, and Optical ESB Bus Repeater Unit. It does not function as a generic power source; its output characteristics are strictly matched to the power requirements of these specific Yokogawa platform components. The module supports a dual-redundant configuration, allowing for concurrent installation of two modules to ensure continuous operation and fault tolerance against individual power supply failures within the DCS chassis.

Frequently Asked Questions (FAQ)

Q: Can the SPW482-13 be used to power generic 24 VDC instruments?

A: No. This module is designed for exclusive use with specific Yokogawa units, including the FCU, FIO Node Unit, and Optical ESB Bus Repeater Unit. It lacks the universal output specifications required for general-purpose instrumentation.

Q: What are the requirements for achieving a redundant power configuration?

A: Redundancy is achieved by installing two SPW482-13 modules within the designated slots of the host unit (FCU or FIO Node). The system automatically manages load sharing between the redundant modules to provide high availability.

Field Installation Guidelines

• Ensure the host unit (FCU or FIO Node) is de-energized before inserting or removing the module to prevent electrical arcing at the exclusive connector interface.
• Align the module with the slot guides and push firmly until the module is fully seated into the backplane; verify that the connection is secure to maintain electrical integrity.
• Do not attempt to modify the exclusive connector pins or adapt the module for use in non-specified hardware, as this will lead to immediate damage to the module and host unit.
• Validate that the 220-240 VAC supply is within the +/- 10% tolerance range; power instability outside these limits may cause the module to shut down or exhibit transient performance issues.
