1756-OA16 数字输出模块  I/O 信号的端点

【产品详情】

1756-OA16 模块是 Allen-Bradley 制造的 ControlLogix 系列模块中的十六 （16） 点数字输出模块。该数字模块的输出电压范围为 74 至 265 伏交流电，频率为 46 至 63 赫兹。每个点、每组和每个模块的额定输出电流分别为 0.5 安培（60 摄氏度）、2 安培（60 摄氏度）和 4 安培（60 摄氏度）。最小负载电流为每点10 mA。此外，1756-OA16 的背板电流在 5.1 伏直流电下为 400 mA，在 24 伏直流电下为 2 mA，构成 2.1 瓦的总背板功耗。此外，最大功耗和热耗散额定值分别为 6.5 瓦（60 摄氏度）和 22.17 BTU/小时。1756-OA16 还支持 2 个可拆卸接线端子，即 1756-TBSH 和 1756-TBNH。

1756-OA16 模块可以设置为不同的工作状态或非工作状态，包括开启状态、关闭状态和最后状态（一种复位功能，可将突然断电的模块重置为上次运行状态）。导通状态下的最大压降为 1.5 V（0.5 安培）和 5.7 V（负载电流小于 50 mA）。另一方面，关断状态下的最大漏电流为每点3 mA。1756-OA16 还具有关闭到开启状态的输出延迟时间，在 60 赫兹时为 9.3 毫秒，在 50 赫兹时，从打开到关闭状态的输出延迟时间为 11 毫秒。为了在点或组保险丝熔断时提醒用户，1756-OA16 模块将使用故障字指示这一点 tag 名称 FuseBlown.另一个故障字标记名称是 FieldPwrLoss，它表示模块输出点的现场电源丢失。1756-OA16 可以在 32 至 140 华氏度的温度范围内运行，并且可以在 -40 至 185 华氏度的温度范围内储存或运输。它可以在相对湿度范围为 5 至 95% 的环境中运行和储存，无冷凝。

该模块可安装在任何兼容的 ControlLogix 机箱 1756-A4、1756/A7、1756-A10、1756-A13 和 1756-A17 上。它还需要一个可拆卸接线端子 （RTB） 作为 I/O 信号的端点。它可以安装在本地或远程 I/O ControlLogix 机箱中。本地 ControlLogix 机箱是安装 ControlLogix 处理器的地方，而远程 I/O 机箱是指通过通信模块与本地机箱通信的机箱。此机箱也称为远程 I/O 或分布式 I/O。该模块的先导额定值为 0.5 A。

【英文介绍】

The 1756-OA16 module is a sixteen (16) point digital output module in the ControlLogix series of modules manufactured by Allen-Bradley. The digital module has an output voltage range of 74 to 265 volts AC and a frequency of 46 to 63 Hertz. The rated output currents for each point, group, and module are 0.5 amps (60 degrees Celsius), 2 amps (60 degrees Celsius), and 4 amps (60 degrees Celsius). The minimum load current is 10 mA per point. In addition, the 1756-OA16's backplane current is 400 mA at 5.1 volts DC and 2 mA at 24 volts DC, making for a total backplane power consumption of 2.1 watts. In addition, the maximum power and heat dissipation ratings are 6.5 watts (60 degrees Celsius) and 22.17 BTU/ hour, respectively. The 1756-OA16 also supports two detachable terminals, 1756-TBSH and 1756-TBNH.

The 1756-OA16 module can be set to different working or non-working states, including on state, off state, and last state (a reset function that resets a module with a sudden power failure to the last operating state). The maximum voltage drop in the on-state is 1.5 V (0.5 amp) and 5.7 V (load current less than 50 mA). On the other hand, the maximum leakage current in the off state is 3 mA per point. The 1756-OA16 also has an output delay time from the off to the On state of 9.3 milliseconds at 60 Hertz and an output delay time from the on to the off state of 11 milliseconds at 50 Hertz. To alert the user when a point or group of fuses has blown, the 1756-OA16 module will indicate this with the fault word tag name FuseBlown. Another fault word tag name is FieldPwrLoss, which indicates a loss of field power at the module's output point. The 1756-OA16 can operate in a temperature range of 32 to 140 degrees Fahrenheit and can be stored or transported in a temperature range of -40 to 185 degrees Fahrenheit. It can be operated and stored in a relative humidity range of 5 to 95% without condensation.

The module can be installed on any compatible ControlLogix chassis 1756-A4, 1756/A7, 1756-A10, 1756-A13, and 1756-A17. It also requires a detachable terminal (RTB) as an endpoint for the I/O signal. It can be installed in a local or remote I/O ControlLogix chassis. The local ControlLogix chassis is where the ControlLogix processor is installed, while the remote I/O chassis is a chassis that communicates with the local chassis through a communication module. This chassis is also known as remote I/O or distributed I/O. The module has a pilot rating of 0.5A.
