【功能描述】

Allen-Bradley 1956-OB16E是一個離散輸出模塊，是ControlLogix可編程自動化控制器(PLC)平臺的一部分。該模塊是一個DC輸出模塊，輸出電壓范圍為10-31.2 VDC，標稱值為24VDC。它帶有十六(16)個輸出通道，分為兩(2)個電子融合組，每組八(8)個通道。該模塊通常用于驅(qū)動24VDC額定設(shè)備，如繼電器線圈、螺線管驅(qū)動設(shè)備、指示燈、警報器和其他類似的電氣負載。

1756-OB16E是一個單槽寬模塊，可與任何1756 ControlLogix控制器兼容使用。它可以安裝到任何1756 ControlLogix機架上，特別是1756-A4；1756-A17；1756年，A10；1756-A13和1756-A17。此外，它還可以作為本地I/O或分布式I/O組件。

1756-OB16E提供每個通道60°C(140°F)時1 A的輸出電流，或每個模塊60°C(140°F)時8 A的輸出電流。它的浪涌電流額定值為2 A，每點10 ms，在0°C(32°F)24伏DC下每2秒重復(fù)一次。此外，模塊的最小負載電流為每通道3 mA。

每組提供內(nèi)置電子熔斷。每個輸出通道的關(guān)到開輸出延遲時間最大為70 s標稱值/1 ms，開到關(guān)延遲時間最大為360 s標稱值/1 ms。它從背板吸取的電流在5v直流時為250 mA，在24v直流時為2 mA，而背板的總功耗要求為1.32瓦，最大功耗為4.1 W(60°C(140°F))。

【英文介紹】

The Allen-Bradley 1956-OB16E is a discrete output module that is part of the ControlLogix Programmable Automation Controller (PLC) platform. The module is a DC output module with an output voltage range of 10-31.2 VDC and a nominal value of 24VDC. It has sixteen (16) output channels divided into two (2) electron fusion groups of eight (8) channels each. The module is typically used to drive 24VDC rated devices such as relay coils, solenoid drive devices, indicators, alarms, and other similar electrical loads.

The 1756-OB16E is a single slot width module that is compatible with any 1756 ControlLogix controller. It can be mounted to any 1756 ControlLogix rack, especially the 1756-A4; 1756-A17; 1756, A10; 1756-A13 and 1756-A17. In addition, it can be used as a local or distributed I/O component.

The 1756-OB16E provides 1 A output current at 60°C(140°F) per channel, or 8 A output current at 60°C(140°F) per module. It has A surge current rating of 2 A, 10 ms per point, repeated every 2 seconds at 24 volt DC at 0°C(32°F). In addition, the minimum load current of the module is 3 mA per channel.

Each set provides built-in electronic fuses. The turn-off to turn-off output delay time of each output channel is up to 70 s nominal value /1 ms, and the turn-off delay time is up to 360 s nominal value /1 ms. The current it draws from the backplane is 250 mA at 5v DC and 2 mA at 24 V DC, while the backplane requires a total power consumption of 1.32 watts and a maximum power consumption of 4.1 W(60°C(140°F)).
