Allen-Bradley 1734- ob8e是1734 Point I/O產(chǎn)品家族的一部分。該模塊是一個(gè)八(8)通道離散輸出模塊，用于為電氣負(fù)載供電，如繼電器，指示燈，電磁驅(qū)動(dòng)設(shè)備和其他在10-28.8 VDC電壓范圍內(nèi)工作的設(shè)備。它用于根據(jù)控制器內(nèi)存中下載的用戶程序，驅(qū)動(dòng)最終控制元件(FCE)執(zhí)行手動(dòng)或自動(dòng)命令。

1734-OB8E是一個(gè)小型，緊湊的輸出模塊，支持DIN導(dǎo)軌安裝。它需要最小的安裝空間，因?yàn)樗奈锢沓叽鐬?6.0 x 12.0 x 75.5 mm (2.21 x 0.47 x 2.97英寸)。它可以連接到任何相鄰的POINT I/O模塊或POINT I/O通信適配器。1734-OB8E實(shí)例數(shù)量的限制取決于控制器的內(nèi)存容量和特定通信協(xié)議和適配器支持的POINT I/O節(jié)點(diǎn)的允許數(shù)量。

1734-OB8E不能作為獨(dú)立設(shè)備操作。它需要一個(gè)POINT I/O通信適配器來管理控制器和POINT I/O模塊之間的雙向傳輸。此外，1734-OB8是總線供電的。它從點(diǎn)I/O總線獲得功率，額定電流為75ma。要建立連接到這個(gè)模塊，它需要使用1734-TB或1734-TBS布線基礎(chǔ)組件。

1734-OB8E每個(gè)輸出額定輸出電流為1.0 A，每個(gè)模塊最大輸出電流不超過3.0 A。最小導(dǎo)通電壓10VDC，最大導(dǎo)通電壓28.8VDC。

1734- ob8e的浪涌電流額定值為2安培，持續(xù)10毫秒，可重復(fù)3秒。它帶有8個(gè)黃色指示燈用于輸出狀態(tài)和2個(gè)綠色/紅色指示燈用于模塊/網(wǎng)絡(luò)狀態(tài)。1734-OB8E的散熱為6.8BTU/小時(shí)。該產(chǎn)品的隔離電壓為50伏，在2500伏直流電下連續(xù)測試60秒。1734-OB8E的外部直流電源為32mA，尺寸約為56.0 x 12.0 x 75.5毫米，接線類別為2個(gè)ON-signal端口。艾倫-布拉德利1734-OB8具有-25至55攝氏度的工作溫度和-40至85攝氏度的非工作溫度。其工作沖擊為30G，非工作沖擊為50G。它的振動(dòng)頻率為5G，頻率為10到500赫茲，相對濕度為5%到95%，不凝結(jié)。

1734-OB8E 八(8)通道離散輸出模塊

The Allen-Bradley 1734-OB8E is part of the 1734 Point I/O product family. This module is an Eight (8) channel discrete output module that is used to energize electrical loads such as relays, pilot lamps, solenoid actuated devices and other devices that operated at a voltage range of 10-28.8 VDC. It is used to actuate Final Control Elements (FCE) to execute manual or automatic commands, according to the downloaded user program in the controller’s memory.

The 1734-OB8E is a small, compact sized output module that support DIN rail mounting. It requires minimum mounting space as it come with physical dimension of 56.0 x 12.0 x 75.5 mm (2.21 x 0.47 x 2.97 in.). It can be attached to any adjacent POINT I/O module or an POINT I/O communication adapter. The limit to the number of instances of 1734-OB8E is based on the controller’s memory capacity and the allowed number of POINT I/O nodes a specific communication protocol and adapter supports.

The 1734-OB8E cannot operated as a standalone device. It requires a POINT I/O communication adapter that manages the bi-directional transfer of between the controller and the POINT I/O module. Additionally, the 1734-OB8 is bus powered. It draws power from the POINT I/O bus with a rated current draw of 75 mA. To establish connections to this module, it requires use of 1734-TB or 1734-TBS wiring base assembly.

The 1734-OB8E has an output current rating of 1.0 A per output, not to exceed 3.0 A, maximum per module. It has minimum ON-state voltage of 10VDC and maximum ON state voltage is 28.8VDC.

The 1734-OB8Ehas a surge current rating of 2 Amps for 10 milliseconds that is repeatable for 3 seconds. It comes with 8 yellow indicator lights for the output status and 2 green/red for the module/network status. The 1734-OB8E has a thermal dissipation of 6.8BTU/hour. The product’s isolation voltage is 50 Volts continuous tested at 2500 Volts DC for 60 seconds. The 1734-OB8E’s external DC power supply is 32mA with an approximate dimension of 56.0 x 12.0 x 75.5 millimeters with a wiring category of 2 ON-signal ports. The Allen-Bradley 1734-OB8 has an operating temperature of -25 to 55 degrees Celsius and a non-operating temperature of -40 to 85 degrees Celsius. Its operating shock is 30G and its non-operating shock of 50G. Its vibration is 5G at 10 to 500 Hertz and relative humidity of 5 to 95%, non-condensing.
