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。

它可以激励或触发感性负载，例如电磁驱动装置，可以是阀门、气缸和其他装置。它也可用于激活继电器甚至电磁接触器，但是，如果模块计划以高浪涌电流为更高的电感负载供电，建议安装隔离电路等隔离电路来保护模块。

该模块与任何 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-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.

It can excite or trigger inductive loads, such as electromagnetic drive devices, which can be valves, cylinders and other devices. It can also be used to activate relays or even electromagnetic contactors, however, if the module plans to power higher inductive loads with high surge currents, it is recommended to install isolation circuits such as isolation circuits to protect the module.

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.
