1756-OF4 直流输出模块
【产品详情】
1756-OB32是艾伦-布拉德利高密度24VDC离散输出模块。该模块用于驱动连接到该模块各通道的输出器件。输出设备可能包括指示灯，继电器，接触器，面板信号器，螺线管，蜂鸣器，警笛，喇叭和其他驱动设备。
该输出模块非常适合用于存在大量输出但空间有限的系统中，用于安装更大或扩展的ControlLogix机箱。占用单槽位，支持安装在本地机箱和远程机箱中。该模块兼容任何ControlLogix处理器，包括最新的ControlLogix版本。
这个1756-OB32提供了32个LED指示灯，用于监控通道驱动。此前面板指示灯是重要的可视化故障排除工具，因为它可以用来确认控制器对连接负载的命令。每个通道都有单独的可配置参数和支持输出强制。此模块仅支持源配置。
与此模块一起使用需要一个可移动终端块(RTB)。适合该输出模块的RTB为1756-TBCH和1756-TBS6H。rtb用于为输出设备提供模块化连接。更换模块时，需要将整个RTB从安装槽位中拔出，并安装到待安装的模块中。这可以防止布线返工，从而更快地进行维护和故障排除。
本模块推荐使用Littelfuse p/n SP001.1003或Schurter p/n 216.800提供的5x20mm 800ma保险丝。接线输出连接需要一个可移动端子块(RTB)。对于该模块，唯一兼容的RTB是保持架夹1756-TBCH和弹簧夹1756-TBS6H。在安装RTB模块之前，请先安装机箱和电源，并将其接地。该模块还具有状态灯指示灯，显示模块状态和单个I/O状态。
适用于1756-OB32模块的通信格式有调度输出数据、输出数据、机架优化、仅听机架优化和仅听输出数据。您还可以配置每个点的故障模式状态和每个点的程序模式状态。您可以选择以下选项:保持上次状态，打开或关闭。请注意，这是默认情况下为所有设置的。
1756-OB32模块的电压类别为12/24V直流电源，工作电压范围为10至31.2V直流。5.1V直流电流为300ma, 24V直流电流为2ma。它还具有1.58W的背板总功率，每点的最大断开状态泄漏电流为0.5 mA，在0.5 a时的最大导通状态电压降为200mv DC。每点的最大浪涌电流为1a，每点10ms，在60摄氏度下每2秒可重复，其最小负载电流为3ma /点。50℃时每个点的最大电流为0.5A, 60℃时为0.35A, 50℃时每个模块的最大电流为16a, 60℃时为10a。该模块还具有250V的连续隔离电压。
1756-OB32模块从关到开的输出延迟时间标称为60秒，最大1毫秒，而从开到关的输出延迟时间标称为200秒，最大1毫秒。它的工作温度范围为0至60摄氏度，非工作温度范围为-40至85摄氏度。

【英文介绍】
The 1756-OB32 is an Allen-Bradley high density 24VDC discrete output module. The module is used to drive output devices connected to each channel of the module. Output devices may include indicators, relays, contactors, panel signalers, solenos, buzzers, sirens, horns, and other driving devices.
This output module is ideal for use in systems with a large number of outputs but limited space for mounting larger or extended ControlLogix enclosures. It occupies a single slot and can be installed in a local or remote chassis. This module is compatible with any ControlLogix processor, including the latest ControlLogix version.
This 1756-OB32 provides 32 LED indicators for monitoring channel drivers. Previously the panel indicator was an important visual troubleshooting tool because it could be used to confirm the controller's command on the connected load. Each channel has individual configurable parameters and supports output coercion. This module supports only source configuration.
Use with this module requires a Removable Terminal block (RTB). The RTBS suitable for this output module are 1756-TBCH and 1756-TBS6H. rtb is used to provide modular connectivity for output devices. When replacing a module, remove the entire RTB from the installation slot and install it into the new module. This prevents wiring rework, allowing for faster maintenance and troubleshooting.
The 5x20mm 800ma fuse provided by Littelfuse p/n SP001.1003 or Schurter p/n 216.800 is recommended for this module. A removable terminal block (RTB) is required for wiring output connections. For this module, the only compatible RTBS are the cage clip 1756-TBCH and the spring clip 1756-TBS6H. Before installing an RTB module, install the chassis and power supply and ground them. The module also has a status light indicator that shows the module status and individual I/O status.
The communication formats applicable to the 1756-OB32 module are dispatch output data, output data, rack optimization, rack optimization only and listen to output data only. You can also configure the fault mode state for each point and the program mode state for each point. You can choose the following options: Keep last state, turn on or off. Note that this is set by default for all.
The 1756-OB32 module has a voltage class of 12/24V DC power supply with an operating voltage range of 10 to 31.2V DC. The 5.1V DC current is 300ma, and the 24V DC current is 2ma. It also has a total backplane power of 1.58W, a maximum on-state leakage current of 0.5 mA per point, and a maximum on-state voltage drop of 200mv DC at 0.5 a. The maximum surge current per point is 1a, 10ms per point, repeatable every 2 seconds at 60 degrees Celsius, and its minimum load current is 3ma/point. The maximum current at each point is 0.5A at 50 ° C, 0.35A at 60 ° C, and the maximum current at 50 ° C is 16a per module and 10a at 60 ° C. The module also has a continuous isolation voltage of 250V.
The 1756-OB32 module has a nominal output delay time of 60 seconds and a maximum of 1 millisecond from off to on, while the output delay time of 200 seconds and a maximum of 1 millisecond from on to off. It has an operating temperature range of 0 to 60 degrees Celsius and a non-operating temperature range of -40 to 85 degrees Celsius.
