1756-IB32 数字I/O模块 ControlLogix系统

【功能描述】

Allen-Bradley 1756-IB32 ControlLogix数字I/O模块也具有250 mA的最大冲击电流额定，在22毫秒内衰减到小于37%而不激活。在关断状态下，其最大电流为2.27 mA，最大电压为5伏。off-to-on和on-to-off过程的输入延迟时间不同。对于off-to-on进程，存在高达380微秒的硬件延迟以及用户可配置的0、1或2毫秒的过滤器时间。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是一款高密度离散输入模块，属于ControlLogix可编程自动化控制器(PAC)产品系列。该模块具有32个输入通道，分为2组，每组16个通道。

它可以安装在本地I/O机架或分布式I/O机箱中，也可以安装在独立或分布式控制系统(DCS)中，例如Allen-Bradley的Plant PAx。当通过硬件配置进入该模块时，模块的参数是可访问的，例如模块的一般属性以及兼容键控和插槽分配等重要参数。该模块还具有可配置的请求数据包间隔(RPI)，模块抑制，对通信失败的反应和通过控制网的计划连接。该模块的每个通道都具有可配置的滤波器设置，以允许对模块的反应时间进行微调。这种调整在离散信号不稳定和暴露于噪声的应用中是有用的。此功能有助于防止误报正负读数。

该模块还具有通过模块信息进行自诊断的能力，可以监控模块的诊断状态，如轻微故障和严重故障。它还可以检测模块连接的ControlLogix背板的状态。

该模块随可移动终端块(RTB)一起发货。这种RTB能够模块化替换有缺陷的模块，并提供易于布线的信号。该模块兼容的RTB为1756-TBCH、1756-TBS6H或36端子RTB。

1756-IB32 数字I/O模块 ControlLogix系统

Allen-Bradley 1756-IB32 is a ControlLogix digital I/O module. As part of the ControlLogix system, this input module has 32 inputs divided into 2 groups of 16 points each. It is mounted to the ControlLogix chassis by using the required removable terminal block housing, or RTB, such as the Allen Bradley 1756-TBCH or 1756-TBS6H. This module occupies a single slot in the ControlLogix chassis and is available in an open chassis type. The 1756-IB32 module has an operating voltage range of 10 to 31.2 volts DC with a nominal input voltage of 24 volts DC. Its voltage class is 12/24 volt DC absorption, 5.1 volt current is 120 mA, 24 volt current is 2 ma, and the total fixed power of the backplane is 0.66 W. The maximum power consumption at 60 ° C is 6.2 W, and the maximum heat dissipation at 60 ° C is 21.1 BTU/ hour.

The Allen-Bradley 1756-IB32 ControlLogix digital I/O module also has a maximum impulse current rating of 250 mA, attenuating to less than 37% in 22 milliseconds without activation. In the off state, it has a maximum current of 2.27 mA and a maximum voltage of 5 volts. The input delay time for the off-to-on and on-to-off processes is different. For off-to-on processes, there is a hardware latency of up to 380 microseconds and a user-configurable filter time of 0, 1, or 2 milliseconds. Switching latency includes hardware latency of up to 420 microseconds, 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 belongs to the ControlLogix Programmable Automation Controller (PAC) family. The module has 32 input channels divided into 2 groups of 16 channels each.

It can be installed in a local I/O rack or distributed I/O chassis, or in a stand-alone or distributed control system (DCS), such as Allen-Bradley's Plant PAx. When entering the module through hardware configuration, the parameters of the module are accessible, such as the general properties of the module and important parameters such as compatibility keying and slot assignment. The module also has configurable request packet Interval (RPI), module suppression, response to communication failures and planned connections through the control network. Each channel of the module has configurable filter Settings to allow fine-tuning of the module's reaction time. This adjustment is useful in applications where discrete signals are unstable and exposed to noise. This feature helps prevent false positive and negative readings.

The module also has the ability to self-diagnose through module information, which can monitor the diagnostic status of the module, such as minor and serious faults. It can also detect the status of the ControlLogix backplane to which the module is attached.

The module is shipped with a Removable Terminal Block (RTB). This RTB enables modular replacement of defective modules and provides easy wiring of signals. Compatible RTBS are 1756-TBCH, 1756-TBS6H, or 36-terminal RTBS.
