1756-IB16 I/O模块 16点直流输入模块

【功能描述】

1756-IB16模块的标称输入电压为直流24伏，电压类别为直流12/24伏。其工作电压范围为10 ~ 31.2伏直流，背板总功率为0.56W。5.1伏直流电流为100毫安。在24伏时，电流为2毫安。该模块还具有250 mA峰值的最大浪涌电流，在22毫秒内衰减至37%，无需激活。其隔离电压为连续250伏。该模块在60℃时的功耗约为5.1瓦，散热为17.39 BTU/小时。该模块的导通电流范围从2.0 mA(10伏直流)到10 mA(31.2伏直流)。在关闭状态下，它的最大电压为5V，最大电流为1.5 mA。模块的输入延迟时间最大为1毫秒的硬件延迟加上用户可配置的滤波器时间(0,1或2毫秒)。它的最大硬件延迟时间为2毫秒，加上用户可配置的过滤器时间(0、1、2、9或18毫秒)。

Allen-Bradley 1756-IB16是一款直流下沉输入模块，工作在24VDC的标称输入电压下。该模块用于24VDCinput信号，但如果安装了适当的插入电路或组件，则仍可用于交流输入电压。

该模块支持单机架，独立控制器配置，用于较小和不太关键的应用。它还可以用于涉及更高程度的关键的大型应用程序，例如远程I/O系统或分布式控制系统(DCS)。

该模块可以作为任何ControlLogix配置的离散输入模块，甚至可以作为Allen-Bradley的PlantPaX DCS平台的离散输入模块。这个模块的安装数量几乎没有限制。实例或安装的数量取决于处理器的内存能力和所使用的物理机箱或可用插槽。

Allen-Bradley 1756-IB16 is a ControlLogix I/O module. This 16-point DC input module, each set of 8 points, can be connected to the 1756 ControlLogix chassis. Compatible removable terminal block housing or RTB are the 1756-TBNH 20-position NEMA RTB and the 1756-TBSH 20-position spring clamp RTB. Before installation, prepare the RTB and ensure that the 1756 chassis and power supply are installed and grounded.

The 1756-IB16 module has a nominal input voltage of 24 volts DC and a voltage class of 12/24 volts DC. Its operating voltage range is 10 to 31.2 volts DC, and the total power of the backplane is 0.56W. The 5.1 volts DC current is 100 mA. At 24 volts, the current is 2 milliamps. The module also has a maximum surge current of 250 mA peak, which decays to 37% in 22 milliseconds without activation. Its isolation voltage is 250 volts continuously. The module has a power consumption of about 5.1 watts at 60 ° C and a heat dissipation of 17.39 BTU/ hour. The conduction current of the module ranges from 2.0 mA(10 V DC) to 10 mA(31.2 V DC). In the off state, it has a maximum voltage of 5V and a maximum current of 1.5mA. The module's input delay time is up to a hardware delay of 1 ms plus a user-configurable filter time (0,1 or 2 ms). It has a maximum hardware latency of 2 milliseconds, plus user-configurable filter times (0, 1, 2, 9 or 18 milliseconds).

The Allen-Bradley 1756-IB16 is a DC sink input module that operates at a nominal input voltage of 24VDC. The module is used for 24VDCinput signals, but can still be used for AC input voltages if the appropriate insertion circuit or component is installed.

The module supports single-stand, independent controller configurations for smaller and less critical applications. It can also be used for large applications that involve a higher degree of critical, such as remote I/O systems or distributed control systems (DCS).

This module can be used as a discrete input module for any ControlLogix configuration and even as a discrete input module for Allen-Bradley's PlantPaX DCS platform. There is almost no limit to the number of installations of this module. The number of instances or installations depends on the memory capacity of the processor and the physical chassis or available slots being used.
