A-B1797-PS2E2/A 电源模块
Allen-Bradley/Rockwell Automation 1797-PS2E2电源是作为Flex Ex和Flex I/O 1797系列的一部分制造的。它适用于本质安全系统。1797-PS2E2电源用于将所有不安全的输入电源与其所属的控制系统隔离,并将该电源限制在IS安全额定水平。它设计有防护等级为IP 65的防火保护外壳。1797-PS2E2电源的工作电压范围为18至32伏直流电。
1797-PS2E2模块是由Allen-Bradley设计和制造的FLEX EX I/O系列本质安全IECEX 24伏直流额定电源模块。1797-PS2E2 PSU(电源装置)是本质安全系统最重要的组件之一。其目的是将输入电源电路与相关电气控制电路的危险区域隔离开来,并阻止电路问题从输入侧转移到输出侧。1797-PS2E2模块的另一项任务是为可访问的能量设置限制并将其调整到定义的安全水平。所有4个输出通道均可独立进行IS限制。
1797-PS2E2安全IECEX PSU模块为其4个输出通道中的每一个提供8.5瓦功率。从这种用于爆炸性环境的特殊设备提供的电压额定值为24伏直流电,这是在危险区域连接到FLEX Ex系统的组件所需的唯一电源。24伏直流电压的输入连接器位于端子1、2、4和5。有4个端子覆盖2个电源输入以实现源输入冗余。可接受的输入电压范围为18至32伏直流电。
Allen-Bradley 1797-PS2E2 4-Ex输出直流电源模块采用IP 65/NEMA 7B级防火外壳,改进了输入和输出的安全终端。输入直流电源密封套是M20x1 5,可以接受直径为6至12毫米的电缆。功率输出密封套(共有4个)为M16x1 5,可以接受4至8毫米宽的电缆。通过这些电缆,电力被传输到执行器、阀门、传感器或变送器。1797-PS2E2模块支持带电插拔,这样可以在系统运行时在危险区域进行电缆连接。

The Allen-Bradley/Rockwell Automation 1797-PS2E2 power supply is manufactured as part of the Flex Ex and Flex I/O 1797 series. It is suitable for intrinsically safe systems. The 1797-PS2E2 power supply IS used to isolate all unsafe input power supplies from the control system to which they belong and to limit this power supply to the IS safe rating level. It is designed with an IP 65 fire protection housing. The 1797-PS2E2 power supply operates from 18 to 32 volts DC. The 1797-PS2E2 module is a FLEX EX I/O series intrinsically safe IECEX 24 volt DC rated power module designed and manufactured by Allen-Bradley. The 1797-PS2E2 PSU (Power Supply Unit) is one of the most important components of an intrinsically safe system. The purpose is to isolate the input power circuit from the danger area of the associated electrical control circuit and prevent the circuit problem from transferring from the input side to the output side.
Another task of the 1797-PS2E2 module is to set limits on the accessible energy and adjust it to defined safe levels. All four output channels can be independently restricted by IS. The 1797-PS2E2 Safety IECEX PSU module delivers 8.5 watts of power to each of its four output channels. The voltage supplied from this special equipment for explosive environments is rated at 24 volts DC, which is the only power supply required to connect components to the FLEX Ex system in hazardous areas. Input connectors for 24 volts DC are located at terminals 1, 2, 4 and 5. There are 4 terminals covering 2 power inputs for source input redundancy. The acceptable input voltage range is 18 to 32 volts DC. The Allen-Bradley 1797-PS2E2 4-Ex Output DC power module features an IP 65/NEMA Class 7B fireproof housing with improved input and output security terminals. The input DC power supply seal is M20X5 and can accept cables with diameters from 6 to 12 mm. The power output seal sleeve (there are four in total) is M16X5 and can accept cables 4 to 8 mm wide. Through these cables, electricity is transmitted to actuators, valves, sensors, or transmitters. The 1797-PS2E2 module supports live plugging, which allows cable connections in hazardous areas while the system is running.
