该模块的输出通道具有可配置的安全状态位置，当控制器的模式更改为程序和控制器故障时。

该模块还具有以下通信格式：输出数据、仅侦听输出数据、机架优化、仅侦听机架优化和定时输出数据。它还允许在“故障”或“程序”中选择每个点的状态，其中“保持最后状态”、“打开”或“关闭”是每个选项的可用选项，并默认为两者设置。

它是一款 12/24V DC 灌/拉输出模块，工作电压范围为 10 至 30V DC。其背板电流在5.1V时为350 mA，在24V时为2.5 mA，背板总功率为1.8 W。其每点的最大电流在 30 摄氏度时为 2 A，在 60 摄氏度时为 1 A（线性降额），而其每个模块的最大电流在 30 摄氏度时为 8 A，在 60 摄氏度时为 4 A（线性降额）。其每点浪涌电流可在 4 A 下每 2 秒重复一次，持续 10 ms。它还具有每点 1 mA 的最小负载电流、1.2V DC（2 A 最大导通状态体积压降）和每点 0.5 mA 的最大关断状态泄漏电流。

1756-OB16I 模块也已在 1350V AC 下进行了 2 秒的例行测试。它具有 250V 的输出至背板连续隔离电压和 125V 的输出至输出连续隔离电压。它还具有从关到开的最大 1 ms 输出延迟时间，从开到关的最长 2 ms 输出延迟时间。1756-OB16I 模块在 60 摄氏度（最大值）下的功耗为 3.6W，其散热为 12.28 BTU/小时。它的工作温度为 0 至 60 摄氏度，非工作温度为 -40 至 85 摄氏度。

Allen-Bradley 1756-OB16I 是一款 1756 ControlLogix 分立式输出模块，支持灌电流和拉电流配置，工作电压类别为 12/24VDC。此输出模块是直接安装到 1756 机箱的单插槽模块。

它有十六 （16） 个独立隔离的通道，只要外部电源连接到 12/24 VDC 电源，就可以将不同的电压源连接到每个输出通道。它也可以按照非隔离接线方案进行端接，其中 DC （+） 和 DC （-） 可以连接到公共电压源。

该输出模块集成了十六 （16） 个 LED 指示器，用于指示模块的操作并描述有源输出通道。当通道处于活动状态时，相应的 LED 通电或亮起，否则为熄灭。该模块的导频额定值为 2A，最大 OFF 至 ON 输出延迟时间为 1 ms，ON 至 OFF 最大输出延迟为 2 ms。该模块可用于为继电器、指示灯、指示灯、警报器、喇叭、蜂鸣器、螺线管等电气负载供电，并可能为其他负载供电。驱动感性负载时，它是非常适合安装外部浪涌保护装置，因为高电感负载具有高浪涌电流。

该模块还具有单独配置的安全状态。当 ControlLogix 处理器从“运行”模式更改为“程序”模式或从“运行”模式更改为“故障”模式时，可以定义这些安全状态。通过定义每个通道的安全状态，可以防止通道不必要的关闭和打开。这样可以安全运行机器或过程并防止事故发生。

【英文介绍】

The Allen-Bradley 1756-OB16I is a ControlLogix DC digital output module with sixteen (16) independent isolation points. It has no internals, however, you can use external IFM to protect the output. The recommended fuse type for this module is 5x20mm 4A quick fuse with the part number SOC p/n MQ2-4A. For the 1756-OB16I module, the compatible remote terminal (RTB) is 1756-TBCH 1756-TBS6H, both of which have 36 pins. RTB is required to provide signal endpoints.

The output channel of this module has a configurable safe state position when the controller's mode changes to program and controller failure.

The module also has the following communication formats: Output data, Listen only Output data, rack optimization, Listen only rack optimization, and timed output data. It also allows the state of each point to be selected in "Fault" or "Programs", where "Keep Last state", "On" or "off" are available options for each option, and are set for both by default.

It is a 12/24V DC feed/pull output module with an operating voltage range of 10 to 30V DC. Its backplane current is 350 mA at 5.1V, 2.5 mA at 24V, and the total backplane power is 1.8 W. Its maximum current per point is 2 A at 30 degrees Celsius and 1 A at 60 degrees Celsius (linear derating), while its maximum current per module is 8 A at 30 degrees Celsius and 4 A at 60 degrees Celsius (linear derating). Each point of the surge current can be repeated every 2 seconds at 4 A for 10 ms. It also has A minimum load current of 1 mA per point, 1.2V DC (2 A maximum on-state volume pressure drop), and a maximum off state leakage current of 0.5 mA per point.

The 1756-OB16I module has also been routinely tested for 2 seconds at 1350V AC. It has an output to backplane continuous isolation voltage of 250V and an output to output continuous isolation voltage of 125V. It also has a maximum output delay time of 1 ms from off to on and a maximum output delay time of 2 ms from on to off. The 1756-OB16I module has a power consumption of 3.6W at 60 degrees Celsius (maximum), and its heat dissipation is 12.28 BTU/ hour. It has an operating temperature of 0 to 60 degrees Celsius and a non-operating temperature of -40 to 85 degrees Celsius.

The Allen-Bradley 1756-OB16I is a 1756 ControlLogix split output module that supports both feed and pull current configurations and operates in the 12/24VDC voltage category. This output module is a single-slot module installed directly into the 1756 chassis.

It has sixteen (16) independently isolated channels, and as long as the external power supply is connected to the 12/24 VDC power supply, different voltage sources can be connected to each output channel. It can also be terminated in a non-isolated wiring scheme where DC (+) and DC (-) can be connected to a common voltage source.

The output module integrates sixteen (16) LED indicators that indicate module operation and describe active output channels. When the channel is active, the corresponding LED is powered on or lit up, otherwise it is extinguished. The module has a pilot rating of 2A with a maximum OFF to ON output delay of 1 ms and a maximum ON to OFF output delay of 2 ms. The module can be used to power electrical loads such as relays, indicator lights, indicators, alarms, horns, buzzers, solenos, and possibly other loads. When driving inductive loads, it is very suitable for installing external surge protection devices, because high inductive loads have high surge current.

The module also has a separately configured security state. These security states can be defined when the ControlLogix processor changes from "Run" to "program" mode or from "Run" to "fault" mode. By defining the security state of each channel, you can prevent the unnecessary closing and opening of channels. This allows safe operation of machines or processes and prevents accidents.
