PS-502-A1 YOKOGAWA Power Supply Module

Product Description (Detailed Explanation)

The PS-502-A1 is designed to convert high-voltage AC mains power into the stabilized DC voltage required by the internal bus of the FA-M3 system. As part of the “Range-free” philosophy, this module is engineered for high density and reliability.

• Integrated Protection: It features robust internal protection circuits to prevent damage to expensive CPU and I/O modules during electrical anomalies.

• System Role: It occupies the dedicated power supply slot on the far left of the FA-M3 base unit.

• Status Monitoring: It includes an LED indicator on the front panel to provide immediate visual confirmation of the power status.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• Wide Input Range: Supports a broad spectrum of global AC power standards (100V–240V), making it suitable for international deployment without the need for additional transformers.

• High Efficiency: Utilizes high-frequency switching technology to minimize heat generation, extending the lifespan of neighboring modules.

• Compact Footprint: Matches the sleek, modular profile of the FA-M3 series, allowing for high-density control cabinet designs.

• Reliability: Engineered for 24/7 industrial operation with a high MTBF (Mean Time Between Failures), ensuring system uptime in critical processes.

• Direct-Mount Design: Provides a secure, vibration-resistant connection to the baseplate, essential for heavy industrial environments.

Precautions (Important Notes)

• Ventilation Clearance: Always maintain the specified clearance above and below the rack. Obstruction of airflow can lead to thermal shutdown or reduced output current.

• Wiring Safety: Ensure the ground terminal (FG) is connected to a high-quality industrial earth ground to minimize noise and prevent electric shock.

• Load Calculation: Before installation, verify that the total current consumption of all modules (CPU, I/O, etc.) on the baseplate does not exceed the 4.3 A capacity of the PS-502-A1.

• Power Sequencing: When performing maintenance, wait at least 1 minute after turning off the power before removing the module to allow internal capacitors to discharge.

Product Applications (Typical Use Cases)

The PS-502-A1 is found in high-speed, high-precision automation environments where Yokogawa FA-M3 PLCs are utilized:

• Semiconductor Manufacturing: Providing stable power for high-speed motion control and cleanroom automation.

• Automotive Assembly: Powering the logic for robotic cells and conveyor synchronization.

• Food and Beverage: Used in bottling and packaging lines where fast cycle times and washdown-resistant cabinets are common.

• Pharmaceuticals: Supporting precise dosing and labeling systems that require highly reliable controller performance.

• Utility Monitoring: Powering RTUs (Remote Terminal Units) for water treatment or electrical substation monitoring.
