1797-PS2E2A 是電源模塊，屬于FLEX EX I/O系列本質(zhì)安全I(xiàn)ECEX 24伏直流額定電源模塊。這款電源模塊在工業(yè)自動化和控制系統(tǒng)領(lǐng)域具有廣泛的應(yīng)用。
該模塊的主要功能是將不安全的輸入電源與其所屬的控制系統(tǒng)隔離，并將電源限制在IS安全額定水平。這有助于確保整個系統(tǒng)的穩(wěn)定性和安全性，防止電路問題從輸入側(cè)轉(zhuǎn)移到輸出側(cè)。1797-PS2E2A的設(shè)計考慮了防火保護(hù)，具有IP 65的防護(hù)等級，這意味著它能夠在較為惡劣的環(huán)境條件下穩(wěn)定運(yùn)行。
此外，1797-PS2E2A模塊的工作電壓范圍為18至32伏直流電，適用于多種不同的應(yīng)用場景。其每一個輸出通道都可以獨(dú)立進(jìn)行IS限制，并能夠為可訪問的能量設(shè)置限制，將其調(diào)整到定義的安全水平。這確保了電源輸出的精確性和安全性。
在安全性方面，1797-PS2E2A模塊還具備看門狗計時器，這是一個安全措施，用于保護(hù)每個GeniusVO連接。通過周期性地重啟這個計時器，總線控制器能夠確保連接的穩(wěn)定性和可靠性。
此外，1797-PS2E2A模塊還具備連接各類歷史數(shù)據(jù)庫的能力，如關(guān)系型數(shù)據(jù)庫如SQL、Oracle，以及生產(chǎn)實時數(shù)據(jù)如OPC SERVER等。這種數(shù)據(jù)集成能力使得模塊在工業(yè)自動化和控制系統(tǒng)領(lǐng)域的應(yīng)用更加廣泛和靈活。
綜上所述，1797-PS2E2A是一款功能強(qiáng)大、安全可靠的電源模塊，適用于需要本質(zhì)安全系統(tǒng)的各種應(yīng)用場景。其獨(dú)特的設(shè)計和特性使其在工業(yè)自動化和控制系統(tǒng)中發(fā)揮著重要的作用。

1797-PS2E2A

The 1797-PS2E2A is a power module belonging to the FLEX EX I/O series intrinsically safe IECEX 24 volt DC rated power module. This power module has a wide range of applications in industrial automation and control systems.
The main function of this module IS to isolate the unsafe input power from the control system to which it belongs and limit the power supply to the IS safe rating level. This helps ensure the stability and security of the entire system, preventing circuit problems from being transferred from the input side to the output side. The 1797-PS2E2A is designed with fire protection in mind and has an IP 65 rating, which means it can operate stably in harsh environmental conditions.
In addition, the 1797-PS2E2A module operates in a voltage range of 18 to 32 volts DC, making it suitable for a variety of different application scenarios. Each of its output channels can be independently limited by IS and can set limits on the accessible energy, adjusting it to a defined safe level. This ensures accuracy and safety of the power output.
In terms of security, the 1797-PS2E2A module also features a watchdog timer, which is a security measure to protect each GeniusVO connection. By periodically restarting this timer, the bus controller ensures the stability and reliability of the connection.
In addition, the 1797-PS2E2A module also has the ability to connect various historical databases, such as relational databases such as SQL, Oracle, and production real-time data such as OPC SERVER. This data integration capability makes the module’s application in the field of industrial automation and control systems more extensive and flexible.
In summary, the 1797-PS2E2A is a powerful, safe and reliable power module for a variety of application scenarios that require intrinsically safe systems. Its unique design and characteristics make it play an important role in industrial automation and control systems.
