1756-IB16 罗克韦尔PLC模块

Allen-Bradley 1756-IB16I是一个ControlLogix离散输入模块。该模块具有十六(16)个独立隔离的输入通道，接受10-30VDC的输入信号电压范围，标称值为24VDC。该模块通常用于连接离散设备，如按钮、开关、辅助触点和其他提供二进制或开关信号状态的设备。

1756-IB16是一个单槽模块，可安装到任何1756 ControlLogix机箱上。它可以连接到任何可用的插槽，除了专用于ControlLogix处理器或通信适配器的lect most插槽。因此，1756-IB16I可用于本地I/O配置以及远程或分布式I/O架构。

1756-IB16I输入通道具有固有的信号转换延迟。对于从关到开的转换，信号延迟最大为1 ms+滤波器时间硬件延迟，其中用户可配置滤波器时间，如0 ms、1 ms或2 ms。对于从开到关的转换，信号延迟由最大4 ms滤波器时间组成，其中可选滤波器时间为0 ms、1 ms、2 ms、9 ms或18 ms。该模块在5.1VDC时的电流消耗为100 mA，在24VDC时为3 mA，总背板功率要求为0.58瓦。

该模块需要使用可拆卸的接线板(RTB)。RTB充当模块的终结点，可以断开和重新连接到支持相同RTB的任何模块。这样，由于不需要移除现有连接，模块更换或迁移得以简化。适用于1756-IB16I的RTB是1756-TBCH和1756-TBS6H。

1756-IB16I的电压类别为12/24V DC电流/电源，工作电压范围为10至30V DC。该模块的标称输入电压为24V DC，60摄氏度时的最大功耗为5 W，热耗散为17.05 BTU/小时。在5.1V时，它的电流消耗为100 mA，在24V时为3 mA。它还具有250 mA峰值的最大浪涌电流(在22 ms内衰减至%3C37%，未激活)。在关断状态下，最大电流为1.5 mA，最大电压为5V。打开状态下模块的电流范围从10V DC时的2 mA到30V DC时的10 mA。该模块在5.1V时的电流消耗为100 mA，在24V时为3 mA。该模块的输入延迟时间根据其状态(从关闭到打开或从关闭到打开)而变化。从“关”到“开”，其延迟时间为最长1 ms的硬件延迟加上用户可选的0 ms、1 ms或2 ms滤波器时间。另一方面，从“开”到“关”，延迟时间为最长4 ms的硬件延迟加上用户可选的0 ms、1 ms、2 ms、9 ms或18 ms滤波器时间。

The Allen-Bradley 1756-IB16I is a ControlLogix discrete input module. The module has sixteen (16) independently isolated input channels and accepts an input signal voltage range of 10-30 VDC with a nominal value of 24 VDC.The module is typically used to interface with discrete devices such as pushbuttons, switches, auxiliary contacts, and other devices that provide binary or switching signal status.

The 1756-IB16 is a single-slot module that can be installed into any 1756 ControlLogix chassis. It can be connected to any available slot except the lec most slot dedicated to a ControlLogix processor or communications adapter. Thus, the 1756-IB16I can be used in local I/O configurations as well as remote or distributed I/O architectures.

The 1756-IB16I input channels have inherent signal transition delays. For switching from off to on, the signal delay is a maximum of 1 ms + filter time hardware delay, where the filter time is user-configurable, such as 0 ms, 1 ms, or 2 ms. For switching from on to off, the signal delay consists of a maximum of 4 ms filter time, where the selectable filter time is 0 ms, 1 ms, 2 ms, 9 ms, or 18 ms. The module’s current at 5.1 VDC consumption is 100 mA at 5.1 VDC and 3 mA at 24 VDC, with a total backplane power requirement of 0.58 watts.

The module requires the use of a removable terminal block (RTB).The RTB acts as a termination point for the module and can be disconnected and reconnected to any module that supports the same RTB. This simplifies module replacement or relocation as there is no need to remove existing connections. The RTBs available for the 1756-IB16I are the 1756-TBCH and 1756-TBS6H.

The 1756-IB16I is available in the 12/24V DC current/supply voltage class and has an operating voltage range of 10 to 30 V DC. The module has a nominal input voltage of 24 V DC, a maximum power consumption of 5 W at 60 degrees Celsius, and a thermal dissipation of 17.05 BTUs/hour. Its current consumption is 100 mA at 5.1 V and 3 mA at 24 V. It also has a maximum inrush current of 250 mA peak (decaying to %3C37% in 22 ms, unactivated). In the OFF state, the maximum current is 1.5 mA and the maximum voltage is 5 V. In the ON state the module’s current ranges from 2 mA at 10 V DC to 10 mA at 30 V DC. The module’s current consumption is 100 mA at 5.1 V and 3 mA at 24 V. The module’s input delay time varies depending on its state (from OFF to ON or from OFF to ON). From “off” to “on”, the delay time is a hardware delay of up to 1 ms plus a user-selectable filter time of 0 ms, 1 ms or 2 ms. On the other hand, from “on” to “off”, the delay time is a hardware delay of up to 4 ms plus a user-selectable filter time of 0 ms, 1 ms, 2 ms, 9 ms, or 18 ms.
