【功能描述】

1797-PS2E2 模塊是由 Allen-Bradley 設(shè)計(jì)和制造的 FLEX EX I/O 系列本質(zhì)安全型 IECEX 24 伏直流額定電源模塊。1797-PS2E2 PSU（電源單元）是本質(zhì)安全系統(tǒng)中最重要的組件之一。其目的是將輸入電源電路與所涉及的電氣控制電路的危險(xiǎn)區(qū)域隔離開(kāi)來(lái)，并禁用電路問(wèn)題從輸入側(cè)到輸出側(cè)的轉(zhuǎn)換。1797-PS2E2 模塊的另一項(xiàng)任務(wù)是設(shè)置可用能量的限制，并將其調(diào)整到定義的安全水平。所有 4 個(gè)輸出通道均可獨(dú)立進(jìn)行 IS 限制。1797-PS2E2 安全 IECEX PSU 模塊為其 4 個(gè)輸出通道中的每個(gè)通道提供 8.5 瓦的功率。這種用于爆炸性環(huán)境的特殊設(shè)備提供的電壓額定值為 24 伏直流電，這是在危險(xiǎn)區(qū)域連接到 FLEX Ex 系統(tǒng)的組件所需的唯一電源。24 伏直流電壓的輸入連接器位于端子 1、2、4 和 5。有 4 個(gè)端子覆蓋 2 個(gè)電源輸入，以實(shí)現(xiàn)源輸入冗余。可接受的輸入電壓范圍為 18 至 32 伏直流電。

Allen-Bradley 1797-PS2E2 4-Ex 輸出直流電源模塊采用 IP 65/NEMA 7B 級(jí)隔爆外殼，改進(jìn)了輸入和輸出的安全端接。輸入直流電源密封套是 M20x1 5，可以接受直徑為 6 至 12 毫米的電纜。電源輸出壓蓋（有 4 個(gè)）為 M16x1 5，可接受 4 至 8 毫米寬的電纜。通過(guò)這些電纜，電力被傳輸?shù)綀?zhí)行器、閥門、傳感器或變送器。1797-PS2E2 模塊支持在通電時(shí)進(jìn)行拆卸和插入，從而可以在系統(tǒng)運(yùn)行時(shí)在危險(xiǎn)區(qū)域進(jìn)行電纜連接。

【英文介紹】

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 hazardous area of the electrical control circuit involved and to disable the conversion of the circuit problem from the input side to the output side. Another task of the 1797-PS2E2 module is to set the limit of available energy and adjust it to a defined safe level. All four output channels can be independently restricted by IS. The 1797-PS2E2 Safety IECEX PSU module provides 8.5 watts of power for each of its four output channels. This special device for explosive environments offers a voltage rating of 24 volts DC, which is the only power needed 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.

Allen-Bradley 1797-PS2E2 4-Ex Output DC power module with IP 65/NEMA Class 7B flame-proof housing, improved input and output safety termination. The input DC power supply seal is M20X5 and can accept cables with diameters from 6 to 12 mm. The power output gland (there are 4) is M16x1 5 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 disassembly and insertion when powered on, allowing cable connections in hazardous areas while the system is running.
