1746-OA8 离散交流输出模块
【产品详情】
Allen-Bradley 1746-OA8是SLC 500交流输出模块。该模块是离散输出模块的一部分，用于为工作电压范围为85-264 VCA，频率为47-63 Hz的电气负载供电。该模块的标称输出电压为120VAC和240VAC，占用1746机箱的单个插槽。
1746-OA8的每个通道提供1.0 a @ 30°C(86°F)或0.50 a @ 60°C(140°F)的连续输出电流，而每个模块的最大连续输出电流为8.0 a @ 30°C(86°F)和4.0 a @ 60°C(140°F)。此外，对于电阻负载，每个通道的ON信号延迟为1ms，对于电阻负载，每个通道的最大OFF延迟信号为11ms。
1746-OA8的背板电流达185 mA @ 5VDC，导通状态输出电压降为1.50V @ 1.0 A。该模块的最小负载电流为10 mA，最大OFF状态泄漏输出电流为2 mA。该模块每个点的最大浪涌电流为10a，持续25ms。
1746- oa8适合1746机箱的任何可用插槽，除了第一个插槽，这是为SLC 500处理器预留的。
本模块不支持RIUP (power Removal and Insertion Under power)功能，安装时必须在无电状态下连接到机箱上。
1746-OA8在其OFF状态下的最大漏电流为2mA，每个输出点上的最小电流负载为10mA。每个输出点的最大电流为1A，在60°C时降至0.5A, 1746-OA8模块上的总电流为8A，但在60°C时可降至4A。在其OFF状态下，它在1A时具有1.50V的降压，并且该模块在25ms时具有10A的输出浪涌电流。1746-OA8的工厂指定工作温度在0到60°C(32到140°F)之间，它必须在5-95%的非冷凝相对湿度中使用，并在40到85°C(-40到185°F)之间的温度下存储。它可以承受57-2000赫兹2.5G的工作振动，可以承受30G的冲击等级。1746-OA8具有NEMA标准ICS 2-230抗噪性，并通过UL和csa认证。

【英文介绍】
Allen-Bradley 1746-OA8 is an SLC 500 AC output module. This module is part of the discrete output module and is used to power electrical loads with an operating voltage range of 85-264 VCA and a frequency of 47-63 Hz. The module has a nominal output voltage of 120VAC and 240VAC and occupies a single slot in the 1746 chassis.
Each channel of the 1746-OA8 provides a continuous output current of 1.0 A@30 °C(86°F) or 0.50 A@60 °C(140°F), while the maximum continuous output current per module is 8.0 A@30 °C(86°F) and 4.0 A@60 °C(140°F). In addition, the ON signal delay per channel is 1ms for resistive loads and the maximum OFF delay signal per channel is 11ms for resistive loads.
The backplane current of the 1746-OA8 is 185 mA@5VDC, and the on-state output voltage drop is 1.50V@1.0A. The module has a minimum load current of 10 mA and a maximum OFF state leakage output current of 2 mA. The maximum surge current at each point of the module is 10a and lasts for 25ms.
The 1746-OA8 fits into any available slot in the 1746 chassis, except for the first slot, which is reserved for the SLC 500 processor.
This module does not support the power Removal and Insertion Under power (RIUP) function and must be connected to the chassis without power during installation.
The 1746-OA8 has a maximum leakage current of 2mA in its OFF state and a minimum current load of 10mA at each output point. The maximum current at each output point is 1A, dropping to 0.5A at 60°C, and the total current on the 1746-OA8 module is 8A, but can drop to 4A at 60°C. In its OFF state, it has a step-down of 1.50V at 1A, and the module has an output surge current of 10A at 25ms. The factory specified operating temperature of 1746-OA8 is between 0 and 60°C(32 to 140°F), it must be used at 5-95% non-condensing relative humidity and stored at a temperature between 40 and 85°C(-40 to 185°F). It can withstand operating vibrations of 57-2000 Hz of 2.5G and can withstand impact ratings of 30G. The 1746-OA8 has NEMA standard ICS 2-230 noise resistance and is UL and csa certified.
