1756-OA8 ControlLogix 输出模块提供 8 个输出（第 0 组和第 1 组各 4 个点）。其“每点故障模式状态”和“每点程序模式状态”可以保留最后一个状态（对于开启状态和关闭状态）。在 60 摄氏度时，每点的额定电流为 2 安培（线性降额），每点的浪涌电流额定值为 20 安培，持续 43 毫秒（在 60 摄氏度下每 2 秒重复一次）。1756-OA8 ControlLogix 输出模块在 60 摄氏度时的最大额定功率为 5.1 瓦，而其散热为每小时 17.39 BTU。其槽宽为 1，每点的最小负载电流为 10 毫安。在关闭状态下，该模块的最大漏电流为每点 3 毫安。1756-OA8 输出模块还支持在 16.7 秒内同步计划输出。

Allen-Bradley 1756-OA8 是一款八 （8） 通道离散交流输出模块，具有两 （2） 个 I/O 组，每个组有四 （4） 个通道。该模块的工作电压范围为 74 至 265 VAC，频率范围为 47/63 Hz。 通道分组的想法是允许模块以不同的电压电平独立运行每个通道，但是，它应该都是交流电压。

这样，一组可以在 120VAC 下运行，而另一组可以在 240VAC 下运行，终端公共端未在内部连接。此外，它还在进行故障排除时提供隔离点。

兼容此模块 1756-A4、1756/A7、1756-A10、1756-A13 和 1756-A17 的 ControlLogix 机箱。该模块需要一个 Allen-Bradley 可拆卸接线端子 （RTB）。RTB 是模块化的，为模块提供端点。使用 RTB，可以方便地连接信号，而无需实际模块。它还允许在模块出现缺陷时快速更换模块，因为它消除了重新布线任务。该模块支持本地或远程 I/O ControlLogix 机箱安装，无论是独立配置还是分布式 I/O 拓扑的一部分。

输出模块用于为电气元件或负载供电，例如螺线管、继电器、指示灯、警报器、喇叭、蜂鸣器、报警器面板、电机、接触器和其他设备。建议安装外部保险丝以提供模块保护，因为该模块不带有保险丝通道。保险丝尺寸参考将取决于每个点的额定电流。S 到 1756-OA8，每点电流为 0.5 A。此模块与任何 ControlLogix 处理器兼容。

它还与任何 ControlLogix 通信模块兼容，包括包含合作伙伴模块。它也可以与 GuradLogix 模块一起工作。

【英文介绍】

The 1756-OA8 module is a ControlLogix digital AC output module manufactured by Allen-Bradley. It has a voltage range of 120 to 240 volts AC (50 to 60 Hz) and an operating voltage range of 74 to 265 volts AC (47 to 63 Hz). It is compatible with Allen-Bradley 1756-TBNH and 1756-TBSH Detachable Terminal blocks (RTB) and has a current rating of 200 mA at 5.1 volts and 2 MA at 24 volts. The total backplane of the 1756-OA8 AC output module is rated at 1.07 watts. The output delay time (from off to on, from on to off) is 9.3 milliseconds at 60 Hz and 11 milliseconds at 50 Hz.

The 1756-OA8 ControlLogix output module provides 8 outputs (4 points each for Group 0 and Group 1). Its "per-point failure mode state" and "per-point program mode state" can retain the last state (for the on state and the off state). At 60 degrees Celsius, the current is rated at 2 amps per point (linear derating) and the surge current is rated at 20 amps per point for 43 milliseconds (repeated every 2 seconds at 60 degrees Celsius). The 1756-OA8 ControlLogix output module has a maximum power rating of 5.1 watts at 60 degrees Celsius, while its heat dissipation is 17.39 BTU per hour. The slot width is 1, and the minimum load current at each point is 10 mA. In the off state, the maximum leakage current of the module is 3 mA per point. The 1756-OA8 output module also supports synchronization of scheduled output in 16.7 seconds.

The Allen-Bradley 1756-OA8 is an eight (8) channel discrete AC output module with two (2) I/O groups, each with four (4) channels. The module operates in a voltage range of 74 to 265 VAC and a frequency range of 47/63 Hz. The idea of channel grouping is to allow the module to run each channel independently at different voltage levels, however, it should all be AC voltage.

In this way, one set can run at 120VAC, while the other can run at 240VAC, with the common end of the terminal not connected internally. In addition, it provides isolation points during troubleshooting.

ControlLogix chassis compatible with this module 1756-A4, 1756/A7, 1756-A10, 1756-A13, and 1756-A17. The module requires an Allen-Bradley Detachable terminal (RTB). RTB is modular and provides endpoints for modules. With RTB, signals can be easily connected without the need for an actual module. It also allows for quick replacement of modules in case of defects, as it eliminates the rewiring task. The module supports local or remote I/O ControlLogix chassis installation, either as a standalone configuration or as part of a distributed I/O topology.

Output modules are used to power electrical components or loads, such as solenos, relays, indicators, alarms, horns, buzzers, alarm panels, motors, contactors, and other equipment. It is recommended to install an external fuse to provide module protection, as the module does not come with a fuse channel. The fuse size reference will depend on the current rating at each point. S to 1756-OA8, 0.5 A current per point. This module is compatible with any ControlLogix processor.

It is also compatible with any ControlLogix communication module, including the inclusion partner module. It can also work with the GuradLogix module.
