1756-OB16IEF Allen-Bradley ControlLogix DC数字隔离快速对等控制输出模块

Allen-Bradley 1756-OB16IEF是ControlLogix DC数字隔离快速对等控制输出模块。该模块是电子融合和保护的基础上每一点，并有16个独立的隔离输出。1756-OB16IEF模块在不到25秒的时间内响应系统转换命令。它还有状态指示器来显示诊断和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盒外壳或RTB。唯一兼容的rtb是1756-TBS6H和1756-TBCH。

该模块有一个故障报告功能，它还有一个附加功能，允许定义在发生错误后，模块从on转换到off之前的持续时间。1756年的OB16IEF 组件是一个CIP同步仅从设备并且它使用CIP同步作为时间戳和调度。因此，需要另一个模块作为网络的主时钟。的其他功能1756-OB16IEF模块包括可配置的点级输出状态、输出数据回声、隔离和非隔离的各种输出模块、多输出点密度、电子熔断以及诊断信息锁存。

可用的故障模式状态是“保持”、“最后状态”、“开”或“关”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”除了设置为“永久”的故障模式外，所有这些状态都默认为“关”

1756-OB16IEF

The Allen-Bradley 1756-OB16IEF is a ControlLogix DC digitally-isolated, fast peer-control output module. The module is electronically fused and protected on a per-point basis, and has 16 individually isolated outputs. The 1756-OB16IEF module responds to commands for system transition in less than 25µS. It also has status indicators to show diagnostic and I/O statuses. A removable terminal block housing, or RTB, is needed before installing the module to the chassis. The only compatible RTBs are the 1756-TBS6H and the 1756-TBCH.

This module has a fault-reporting feature and it has an additional feature that allows the definition of the time duration before the module transitions from on to off after an error happens. The 1756-OB16IEF module is a CIP Sync slave-only device and it uses the CIP Sync for timestamps and scheduling. As such, another module is needed to act as the master clock of the network. Other features of the 1756-OB16IEF module include configurable point-level output states, output data echo, isolated and non-isolated varieties of output modules, multiple output point densities, electronic fusing, and a diagnostic information latch.

Available Fault-Mode states are “Hold,” “Last State,” “On,” or “Off.” The available Fault Mode durations are 1, 2, 5, 10 s, and “Forever.” The final state after Fault Mode can either be “Off” or “On.” All these states have “Off” as default except for Fault Mode set at “Forever.”
