【产品详情】

Allen-Bradley 1756-IA16 是一款ControlLogix I/O 模块。该交流数字输入模块是隔离型，具有显示输入和通信状态以及模块运行状况的显示屏。该模块的输入通道是单独隔离的，这些通道也单独额定为 125 伏连续输入。该模块直接连接到 ControlLogix 机箱。与该模块兼容的可拆卸接线端子外壳是 1756-TBCH 和 1756-TBS6H。

输入电压和电压tage 该模块的类别均为 120 伏交流电。24 伏时的电流消耗为 3 毫安，5.1 伏时的电流消耗为 125 毫安。该模块的工作电压范围为 79 至 132 伏交流电和 47 至 63 赫兹。60 摄氏度时的最大功耗为 4.9 瓦，热耗散为每小时 16.71 BTU。浪涌电流最大为 250 毫安，背板总功率为 0.71 瓦。螺丝到背板输入延迟时间如下：硬件延迟最大为 10 毫秒加上用户可选择的滤波时间（1 或 2 毫秒），硬件延迟的最大时间为 8 毫秒，用户可选择的滤波时间为 9 至 18 毫秒。最大关断级电压为 20 V，最大电流为 2.5 毫安。对于导通状态，在 79 伏交流电时最小值为 5 毫安，范围为 47 至 63 赫兹，而在 132 伏交流电时最大值为 15 毫安，范围为 47 至 63 赫兹。

Allen-Bradley 1756-IA16I 是一款十六 （16） 通道分立式交流输入模块， 具有独立隔离的通道。该模块在标称输入电压下工作tage 为 120VAC，频率为 50/60 Hz。 此模块安装在本地或远程 I/O ControlLogix 机箱上。

本地 ControlLogix 机箱是指安装了 ControlLogix 处理器的组件，而远程 I/O 机箱是指通过通信适配器与本地机箱通信的 ControlLogix 机箱。

可编程逻辑控制器 （PLC） （如 ControlLogix 系统）使用离散输入模块与过程或机器连接，并接收每个单独输入的二进制状态，即 OFF 和 ON。这是必要的，因为Allen-Bradley控制器通过检查输入的状态（包括连接到1767-IA16I的信号）来开始逻辑执行。

该模块与任何 ControlLogix 处理器兼容。它还与任何 ControlLogix 通信适配器兼容，用于实现远程 I/O 应用程序。

该模块使用 36 点可拆卸接线端子 （RTB） 来连接信号，并允许模块化更换有缺陷的模块，而无需完全重新布线。由于该模块的通道是单独隔离的，因此每个通道都有单独的公共通道，这使得该模块可用于存在直接交流公共端的应用。

该模块具有前面板指示灯，可提供每个通道的状态。每当为通道提供适当的信号时，专用的 LED 指示灯将被激活，以确认模块已接收到信号。

【英文介绍】

The Allen-Bradley 1756-IA16 is a ControlLogix I/O module. The AC digital input module is isolated and has a display that displays input and communication status as well as module health. The module's input channels are individually isolated and these channels are also individually rated for 125 volts continuous input. This module connects directly to the ControlLogix chassis. Removable terminal housings compatible with this module are 1756-TBCH and 1756-TBS6H.

Input Voltage and Voltage tage The class of this module is 120 volts AC. The current consumption at 24 volts is 3 MA and the current consumption at 5.1 volts is 125 MA. The module operates in a voltage range of 79 to 132 volts AC and 47 to 63 Hertz. The maximum power consumption at 60 degrees Celsius is 4.9 watts and the heat dissipation is 16.71 BTU per hour. The maximum inrush current is 250 mA and the total backplane power is 0.71 watts. The screw to backplane input delay times are as follows: The maximum hardware delay is 10 ms plus the user selectable filtering time (1 or 2 ms), the maximum hardware delay time is 8 ms, and the user selectable filtering time is 9 to 18 ms. The maximum turn-off stage voltage is 20 V and the maximum current is 2.5 MA. For the on-state, the minimum is 5 mah at 79 AC and ranges from 47 to 63 Hz, while the maximum is 15 mah at 132 AC and ranges from 47 to 63 Hz.

The Allen-Bradley 1756-IA16I is a sixteen (16) channel discrete AC input module with independently isolated channels. The module operates at a nominal input voltage with a tage of 120VAC and a frequency of 50/60 Hz. This module is installed in a local or remote I/O ControlLogix chassis.

A local ControlLogix chassis is a component that houses the ControlLogix processor, while a remote I/O chassis is a ControlLogix chassis that communicates with the local chassis through a communication adapter.

Programmable logic controllers (PLCS), such as ControlLogix systems, use discrete input modules to connect to processes or machines and receive binary states for each individual input, i.e., OFF and ON. This is necessary because the Allen-Bradley controller starts the logical execution by checking the state of the input, including the signal connected to 1767-IA16I.

This module is compatible with any ControlLogix processor. It is also compatible with any ControlLogix communication adapter for implementing remote I/O applications.

The module uses 36-point detachable terminal blocks (RTB) to connect signals and allows for modular replacement of defective modules without the need for complete rewiring. Since the module's channels are individually isolated, each channel has a separate public channel, which makes the module useful for applications where there is a direct AC public end.

The module has front panel indicators that provide the status of each channel. Whenever the appropriate signal is provided for the channel, a dedicated LED indicator will be activated to confirm that the module has received the signal.
