1756-IB32数字量输入模块

Allen-Bradley 1756-IB32是一个ControlLogix数字输入/输出模块。作为ControlLogix系统的一部分，该输入模块有两组32个输入，每组16个点。通过使用所需的可拆卸接线盒外壳或RTB，如Allen-Bradley 1756-TBCH或1756-TBS6H，将其安装到ControlLogix机箱上。该模块占用ControlLogix机箱的一个插槽，并提供开放式外壳类型。1756-IB32模块的工作电压范围为10至31.2伏DC，标称输入电压为24伏DC。它的电压类别为12/24伏DC吸电流，5.1伏时的电流消耗为120 mA，24伏时为2 mA，总背板额定功率为0.66 W。60摄氏度时的最大功耗为6.2 W，而60摄氏度时的散热为21.1 BTU/小时。

Allen-Bradley 1756-IB32 control logix数字I/O模块还具有250 mA的最大浪涌电流额定值，在未激活的情况下，该值在22毫秒内衰减至37%以下。在关断状态下，其最大电流为2.27 mA，最大电压为5伏。关到开和开到关过程的输入延迟时间不同。对于从关到开过程，硬件延迟高达380微秒，加上用户可配置的0、1或2毫秒的滤波时间。开关延迟时间包括高达420微秒的硬件延迟时间，加上用户可配置的0、1、2、9或18毫秒的滤波器时间。

Allen-Bradley 1756-IB32是一种高密度离散输入模块，属于可编程自动化控制器(PAC)的ControlLogix产品系列。该模块具有三十二(32)个输入通道，分成两(2)组，每组十六(16)个通道。

The Allen-Bradley 1756-IB32 is a ControlLogix digital input/output module. As part of a ControlLogix system, this input module has two sets of 32 inputs with 16 points each. It is mounted to the ControlLogix chassis by using the required removable junction box enclosure or RTB, such as the Allen-Bradley 1756-TBCH or 1756-TBS6H. The module occupies one slot in the ControlLogix chassis and is available in an open housing type.The 1756-IB32 module operates from 10 to 31.2 volts DC, with a nominal input voltage of 24 volts DC.It draws current in the voltage category of 12/24 volts DC, with a current consumption of 120 mA at 5.1 volts and 2 mA at 24 volts, and a total backplane power rating is 0.66 W. Maximum power consumption is 6.2 W at 60 degrees Celsius, while heat dissipation is 21.1 BTU/hour at 60 degrees Celsius.

The Allen-Bradley 1756-IB32 control logix digital I/O module also has a maximum inrush current rating of 250 mA, which attenuates to less than 37% in 22 milliseconds when inactive. In the off state, it has a maximum current of 2.27 mA and a maximum voltage of 5 volts. The input delay time is different for the off-to-on and on-to-off processes. For the off-to-on process, the hardware delay is up to 380 microseconds, plus a user-configurable filter time of 0, 1, or 2 milliseconds. The switching delay time includes up to 420 microseconds of hardware delay time, plus user-configurable filter times of 0, 1, 2, 9, or 18 milliseconds.

The Allen-Bradley 1756-IB32 is a high-density discrete input module that is part of the ControlLogix family of programmable automation controllers (PACs). The module has thirty-two (32) input channels divided into two (2) groups of sixteen (16) channels each.
