电源输入：模块通常接受来自设施中可用主电源的输入电压，例如 AC（交流电）或 DC（直流电）电压。

功率输出：该模块将功率分配给控制系统的不同部分，确保每个组件都能获得其运行所需的适当电压和电流水平。这包括为控制器、I/O 模块、通信模块和其他设备供电。

冗余和容错：在关键控制系统中，电源模块通常包含冗余功能以确保不间断供电。冗余电源模块可以在主模块发生故障时提供备用电源，提高系统的可靠性和可用性。

保护机制：电源模块可能包括保护功能，以防止与电源相关的问题，例如过压、欠压、过流、短路和电涌。这些机制有助于防止损坏控制系统组件并确保安全稳定运行。

Power input: Modules typically accept input voltage from the main power supply available in the facility, such as AC (alternating current) or DC (direct current) voltage.

Power output: This module distributes power to different parts of the control system, ensuring that each component gets the appropriate voltage and current levels it needs to operate. This includes powering controllers, I/O modules, communication modules and other devices.

Redundancy and fault tolerance: In critical control systems, power modules often include redundancy features to ensure uninterrupted power supply. Redundant power modules provide backup power when the active power module fails, improving system reliability and availability.

Protection mechanisms: Power modules may include protection features to prevent power-related problems such as overvoltage, undervoltage, overcurrent, short circuit, and power surge. These mechanisms help prevent damage to control system components and ensure safe and stable operation.
