1797-PS2E2A 高性能可编程逻辑控制器

1797-PS2E2A是一个由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。这个电源模块的主要目的是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。

它具有IP 65的防护等级，这意味着它具有一定的防尘和防水能力。此外，它的工作电压范围为18至32伏直流电。

1797-PS2E2A电源模块的一个重要功能是，它能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。同时，这个电源模块为其4个输出通道中的每一个提供8.5瓦功率。

此外，1797-PS2E2A A-B还可以通过手持式监视器改变串行总线地址。并且，它配备了一个看门狗计时器，作为一个安全措施，保护每个GeniusVO连接。每一个Genius网络最多可以连接30个Genius设备。

此外，1797-PS2E2A RTIP还可以连接各类历史数据库，如关系型数据库如SQL、Oracle，以及生产实时数据如OPC SERVER，还可以连接报警数据、质量数据等。

总的来说，1797-PS2E2A是一个功能强大的本质安全电源模块，具有高度的安全性和灵活性，适用于各种工业环境和应用场景。

The 1797-PS2E2A is a FLEX EX I/O series intrinsically safe IECEX 24 volt DC rated power module designed and manufactured by Allen-Bradley. The main purpose of this power supply module IS to isolate all unsafe input power from the control system to which it belongs and limit this power supply to the IS safe rating level.

It has an IP 65 protection rating, which means it has some dust and water resistance. In addition, it operates in a voltage range of 18 to 32 volts DC.

An important function of the 1797-PS2E2A power module is that it can set limits on the amount of accessible energy and adjust it to defined safe levels. All four output channels can be independently restricted by IS. At the same time, this PSU provides 8.5 watts of power to each of its four output channels.

In addition, the 1797-PS2E2A A-B can also change the serial bus address via A handheld monitor. And, it is equipped with a watchdog timer as a security measure to protect each GeniusVO connection. Each Genius network can connect up to 30 Genius devices.

In addition, the 1797-PS2E2A RTIP can also connect to various historical databases, such as relational databases such as SQL, Oracle, and production real-time data such as OPC SERVER, alarm data, quality data, etc.

Overall, the 1797-PS2E2A is a powerful intrinsically safe power module with a high degree of safety and flexibility for a variety of industrial environments and application scenarios.
