1756-OB16IEF 数字隔离控制输出模块 具有 16 个独立隔离的输出

【产品详情】

Allen-Bradley 1756-OB16IEF是一款ControlLogix DC数字隔离、快速对等控制输出模块。该模块以电子方式熔断并按点进行保护，并具有 16 个独立隔离的输出。1756-OB16IEF模块可在不到25μS的时间内响应系统转换命令。它还具有状态指示器，用于显示诊断和 I/O 状态。在将模块安装到机箱之前，需要一个可拆卸的接线端子外壳 （RTB）。唯一兼容的 RTB 是 1756-TBS6H 和 1756-TBCH。

该模块具有故障报告功能，并且具有附加功能，允许定义错误发生后模块从打开转换到关闭之前的持续时间。1756-OB16IEF 模块是 CIP Sync 仅从设备，它使用 CIP Sync 进行时间戳和调度。因此，需要另一个模块来充当网络的主时钟。1756-OB16IEF模块的其他功能包括可配置的点级输出状态、输出数据回波、隔离式和非隔离式输出模块、多输出点密度、电子熔断和诊断信息锁存器。

可用的故障模式状态为“保持”、“上次状态”、“打开”或“关闭”。可用的故障模式持续时间为 1、2、5、10 秒和“永久”。故障模式后的最终状态可以是“关闭”或“打开”。所有这些状态的默认值均为“关闭”，但故障模式设置为“永久”。

1756-OB16IEF模块的先导额定值为4 A浪涌。它的电压类别为 12/24V DC 灌/拉，工作电压范围为 10-30V DC，24V 时电流消耗为 3 mA，5.1V 时电流消耗为 320 mA，背板总功率为 1.7 W。其脉宽调制 （PWM） 周期时间为最小 1 ms/最大 1 小时，PWM 导通时间为最小 200 μs/最大 1 小时，PWM 导通时间精度为 +/-20 μs。该模块的最小负载电流为每点 1 mA，而其浪涌电流为 4 A，持续 10 ms，每 2 秒可重复一次。它还具有 250V 的连续隔离电压。该模块每点的最大关断状态泄漏电流为 < 0.1 mA，最大导通状态压降为 0.2V DC （1 A） 和 0.4V DC （2 A）。在 45 摄氏度（最多 4 个通道）时，其每点的最大电流为 2 A，但在 60 摄氏度时为 1 A。在 60 摄氏度时，每个模块的最大电流为 16 A，每通道最大电流为 1 A，在 45 摄氏度时，最大电流为 8 A，每通道最大电流为 2 A。

【英文介绍】

Allen-Bradley 1756-OB16IEF is a ControlLogix DC digital isolation, fast peer-to-peer control output module. The module is electronically fused and point-to-point protected and has 16 independently isolated outputs. The 1756-OB16IEF module responds to system conversion commands in less than 25μS. It also has status indicators to show diagnostic and I/O status. A detachable terminal housing (RTB) is required before installing the module into the case. The only compatible RTBS are the 1756-TBS6H and 1756-TBCH.

The module has a fault reporting function and has additional features that allow you to define the duration of the module before it switches from on to off after an error occurs. The 1756-OB16IEF module is CIP Sync only for slave devices, which uses CIP Sync for time stamping and scheduling. Therefore, another module is needed to act as the master clock of the network. Additional features of the 1756-OB16IEF module include configurable point-level output status, output data echo, isolated and non-isolated output modules, multiple output point density, electronic fuse and diagnostic information latches.

The available fault mode states are Hold, Last Status, On, or Off. The available failure mode durations are 1, 2, 5, 10 seconds and "Permanent". The final state after failure mode can be "Off" or "On". The default value for all of these states is "Off," but the failure mode is set to "Permanent."

The 1756-OB16IEF module has A pilot rating of 4 A surges. Its voltage category is 12/24V DC perfusion/pull, operating voltage range is 10-30V DC, current consumption is 3 mA at 24V, current consumption is 320 mA at 5.1V, and total backplane power is 1.7 W. The pulse width modulation (PWM) cycle time is minimum 1 ms/ maximum 1 hour, the PWM on-time is minimum 200 μs/ maximum 1 hour, and the PWM on-time accuracy is +/-20 μs. The module has A minimum load current of 1 mA per point, while its surge current is 4 A for 10 ms and can be repeated every 2 seconds. It also has a continuous isolation voltage of 250V. The module has A maximum turn-off leakage current of < 0.1 mA at each point and A maximum on-state voltage drop of 0.2V DC (1 A) and 0.4V DC (2 A). At 45 degrees Celsius (up to 4 channels), its maximum current per point is 2 A, but at 60 degrees Celsius it is 1 A. At 60 degrees Celsius, the maximum current per module is 16 A and 1 A per channel, and at 45 degrees Celsius, the maximum current is 8 A and 2 A per channel.
