Product Description

The Power Module utilizes sophisticated switched-mode power supply (SMPS) technology to deliver clean and reliable power:

• Voltage Conversion: Converts the external primary power source (e.g., $120/230 text{V AC}$ or $24 text{V DC}$) into the regulated secondary voltage required for the backplane bus and internal module circuits (e.g., $5 text{V DC}$).

• Power Regulation: Provides a highly regulated output voltage, maintaining stability despite fluctuations in the primary supply, which is critical for sensitive electronics.

• Protection Features: Includes integrated protection mechanisms against common electrical faults, such as overload, short-circuit, and over-voltage.

• Diagnostics: Features status indicators (LEDs) and often communicates diagnostic information to the CPU regarding its operational status, potential faults, or overload conditions.

• Hold-up Time: Designed with internal capacitance to bridge brief power interruptions, maintaining system operation during short outages.

Product Parameters

The technical parameters define the module’s capacity and operational range:

Product Advantages

• System Integrity: Ensures a stable and clean power source for the automation system, preventing logic errors and communication faults that can result from poor power quality.

• High Reliability: Built with industrial-grade components to withstand electrical stresses and harsh environmental conditions, providing a high Mean Time Between Failures (MTBF).

• Integration and Monitoring: Seamlessly integrates into the automation backplane, allowing for central monitoring and configuration via the engineering software.

• Energy Efficiency: High-efficiency conversion minimizes energy wastage and reduces the heat load inside the control cabinet.

Important Considerations (Notes)

• Sizing and Load Calculation: The Power Module’s output power must be sufficient to supply the total calculated power consumption of the CPU, all I/O modules, and any connected field devices. Always include a margin for future expansion.

• Thermal Management (Derating): Observe the manufacturer’s temperature derating curves. Operating the module at high ambient temperatures or mounting it without proper airflow will reduce its maximum available output current/power.

• Redundancy: For critical applications, multiple Power Modules should be used in a redundant configuration to ensure continuous operation in case of a single module failure.

• Grounding and Fusing: Proper earthing and the use of correctly rated input fusing are essential for the module’s safety, performance, and compliance.

Product Applications

The Power Module is essential for powering various elements within an automation infrastructure:

• Centralized PLC Racks: Providing the backbone power for the CPU and all locally mounted I/O modules.

• Distributed I/O Stations: Supplying power to remote I/O devices (input, output, and communication modules) placed closer to field equipment.

• Safety Systems: Supplying highly reliable, separate power feeds for dedicated safety-related components.

• Industrial Networks: Providing power for communication processors and network switches mounted within the control cabinet.
