1797- PS2E2模块是由Allen- Bradley设计和制造的FLEX EX /0系列本质安全IECEX 24伏DC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。其期的是将输入 电源电路与相关电气控制电路的危险区域隔离，并禁止电路问题从输入侧转移到输出侧。1797-PS2E2模块
的另-项任务是设置可用能量的限值，并将其调整至规定的安全水平。所有4个输出通道可以独立地被限制。1797-PS2E2安全IECEX PSU模块为其4
个输出通道中的每个通道提供8.5瓦的功率。这种用于爆炸性环境的特殊装置输出的额定电压为24伏DC,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DC电压的输入接头位于接线端1、2、4和5。 有4个端子覆盖2个电源输入，用于电源输入冗余。可接受的输入电压范围是18
到32伏DC。
1797-PS2E2
Allen-Bradley 1797- PS2E24-Ex输出DC电源模块采用IP 65/NEMA 7B级防火外壳，该外壳改进了输入和输出的安全终端。输入DC电源压盖是一个
M20x1 5,可以接受直径为6至12毫米的电缆。功率输出压盖(共有4个)为M16x1 5,可接受4至8毫米宽的电缆。通过这些电缆，电力传输到执行
器、阀门、传感器或变送器。1797- PS2E2模块支持带电拆卸和插入,这使得系统运行时能够在危险区域进行电缆连接。

The 1797-PS2E2 module is a FLEX EX /0 series intrinsically safe IECEX 24 volt DC rated power module designed and manufactured by Allen-Bradley. 1797-PS2E2 PSU(Power supply unit is intrinsically safe
One of the most important components of the system. The goal is to isolate the input power circuit from the hazardous area of the associated electrical control circuit, and to prohibit the transfer of circuit problems from the input side to the output side. 1797-PS2E2 module
The other task is to set the limit of available energy and adjust it to the specified safe level. All 4 output channels can be restricted independently. 1797-PS2E2 The IECEX PSU module is its 4
Each of the output channels provides 8.5 watts of power. This special unit for explosive environments outputs a rated voltage of 24 volts DC, which is the component connected to the FLEX Ex system in hazardous areas
The only power source needed. Input connectors for 24 volts DC are located at terminals 1, 2, 4 and 5. There are 4 terminals covering 2 power inputs for power input redundancy. The acceptable input voltage range is 18
To 32 volts DC.
The Allen-Bradley 1797-PS2E24-Ex Output DC power module features an IP 65/NEMA Class 7B fireproof housing with improved input and output security terminals. Input DC power supply gland is one
The M20x1 5 can accept cables with diameters from 6 to 12 mm. The power output gland (of which there are four) is M16X5 and accepts cables 4 to 8 mm wide. Through these cables, power is transmitted to the execution
Device, valve, sensor or transmitter. The 1797-PS2E2 module supports live disassembly and insertion, which enables cable connections in hazardous areas while the system is in operation.
