Description

The Yokogawa SPW481-13 S1 is a high-reliability power supply module designed specifically for the ProSafe-RS safety instrumented system (SIS). This module functions by converting a 100 to 120 V AC input supply into stable, regulated dual-redundant +5 V DC and +24 V DC outputs required to energize the safety control station CPU modules, I/O modules, and system infrastructure. Engineered for continuous industrial operation, the Yokogawa SPW481-13 S1 supports hot-swapping and features integrated protective circuitry to ensure high system availability, safety loop continuity, and resilient fault containment across demanding automation environments.

Features

Dual-Redundant Support: Accommodates dual-redundant insulated output operations to maximize safety system uptime.
Hot-Swappable Design: Enables maintenance personnel to replace modules without disconnecting system power or causing control interruptions.
Comprehensive Fault Containment: Equipped with internal monitoring and protective circuitry against unsafe power supply exceptions.
Industrial Construction: Ruggedly designed to fit seamlessly into specialized ProSafe-RS control racks for prolonged operation.

Applications

High-integrity emergency shutdown (ESD) systems
Fire and gas (F&G) system power architecture
Burner management systems (BMS) in power generation
Critical interlock networks within petrochemical plants
Distributed safety control system node power management

Installation Guidelines

Ensure the primary 100-120 V AC power line matches the input terminal requirements before performing power-on diagnostics.
Secure the module firmly into its designated slot within the ProSafe-RS safety control unit or safety node unit rack.
Ensure adequate ventilation and clearance space around the cabinet enclosure to maintain nominal operating temperature thresholds.
Ground the protective conductor terminal or functional grounding terminal according to official plant standard wiring instructions to minimize EMI/RFI issues.
