PS-502-01 Yokogawa

PS-502-01 Yokogawa Output I/O module

Product  Description：

The PS-502-01 acts as a critical infrastructure component in the Yokogawa DCS architecture. It is typically installed in an I/O rack or a remote node to convert the incoming AC or DC power source into the specific levels required by the system's backplane. Its design emphasizes high availability and industrial-grade reliability, which are hallmarks of the Yokogawa brand. The module is engineered to provide a clean, noise-filtered power output to prevent interference with sensitive analog or digital signals within the RIO system.

Product Parameters

• Input Voltage Range: Primarily designed for 220 V to 240 V AC (with a broad tolerance range, typically $170 \text{ V}$ to $264 \text{ V}$ depending on the specific sub-model configuration).

• Input Frequency: Standard 50/60 Hz operation.

• Output Voltage: Provides a regulated internal system voltage (typically $5 \text{ VDC}$ for logic and $24 \text{ VDC}$ for field supply or internal signaling).

• Power Capacity: Approximately $50 \text{ W}$ to $100 \text{ W}$ peak output, depending on the load configuration of the remote node.

• Mounting Type: Rack-mounted or base-plate mounted depending on the specific RIO node housing.

• Heat Dissipation: Natural air convection cooling is generally required.

• Redundancy Support: Fully compatible with redundant power configurations where two modules are used in parallel to prevent system failure.

Product Advantages

• High Reliability: Built with high-quality industrial components that offer a high Mean Time Between Failures (MTBF), ensuring continuous plant operation.

• Seamless Integration: Specifically designed for the CENTUM series, meaning there are no compatibility issues with the backplane or adjacent I/O modules.

• Redundancy Capability: The PS-502-01 can be installed in pairs. If one module fails, the second module takes over the full load instantly without causing a system reset or process interruption.

• Diagnostic Features: Includes internal monitoring circuitry that can report the status of the power supply back to the DCS operator station, allowing for predictive maintenance.

• Noise Suppression: Incorporates advanced filtering to protect the DCS from electrical surges and electromagnetic interference (EMI) common in industrial environments.

Important Considerations

• Installation Environment: Ensure the module is installed in a location that meets the specified temperature and humidity limits (typically $0\degree\text{C}$ to $55\degree\text{C}$). Overheating is a primary cause of shortened power supply life.

• Proper Grounding: The module must be securely grounded to the system earth to ensure both personnel safety and signal integrity.

• Hot-Swapping: While Yokogawa systems often support online replacement, always verify the specific rack configuration and safety procedures before removing a power module while the system is live.

• Voltage Selection: Before applying power, verify that the input voltage matches the module's rating (e.g., $100\text{--}120 \text{ V}$ vs. $220\text{--}240 \text{ V}$) to avoid permanent damage.

• End of Life: As part of the older CS 3000 infrastructure, users should check for spare part availability, as Yokogawa eventually transitions older modules to "limited support" status.

Product Applications

• Oil and Gas Refineries: Powering remote I/O nodes situated across large refining complexes to monitor pressure, temperature, and flow.

• Chemical Processing: Providing stable power for control loops in hazardous environments where system uptime is critical for safety.

• Power Generation: Used in plant-wide control systems for thermal or hydroelectric plants to manage turbine and boiler data.

• Water and Wastewater Treatment: Supporting distributed nodes in utility plants for long-distance data acquisition and valve control.

• Pulp and Paper Mills: Ensuring the continuous operation of large-scale automated machinery by providing reliable power to the local control bus.
