1771-IQC 数字输入模块 具有输入滤波功能

【产品详情】

1771-IQC输入模块是由艾伦-布拉德利/罗克韦尔自动化公司在PLC 5系列中制造的数字输入模块。该直流可选输入模块工作在5至30伏直流电压范围内，该模块是一个8点可选输入模块。像这样的Bulletin 1771数字直流输入模块是为将来自用户设备的直流信号转换为处理器使用的正确逻辑电平而设计的。本系列和1771-IQC模块的典型输入设备的一些功能包括接近开关、选择开关、限位开关、按钮开关和浮动开关。直流输入模块每个模块有多种输入端子，兼容当前机箱，包括1171-A1B、A2B、A3B、A3B1、A4B、AM1和AM2机箱。它具有8个输入图像位，并与½插槽，1插槽和2插槽寻址兼容。

Allen-Bradley 1771-IQC数字输入模块具有输入滤波功能，有助于限制由电子噪声或触点反弹引起的电压瞬变的影响。如果不进行滤波，电压瞬变可能产生假数据。通过光电隔离保护1771-IQC模块的其他组件免受可能的电瞬变损坏，包括模块逻辑电路，背板电路和整个系统。但是，Bulletin 1771产品线中的一些模块允许用户根据特定模块规格设置输入滤波器时间跳线。此外，该模块兼容已取代的机箱系列，包括1771-A1、1771-A2和1771-A4机箱。然而，它不需要有条件的模块放置。

【英文介绍】

The 1771-IQC input module is a digital input module manufactured by Allen-Bradley/Rockwell Automation in the PLC 5 series. The DC optional input module operates in the DC voltage range of 5 to 30 volts. The module is an 8-point optional input module. Bulletin 1771 digital DC input modules like this one are designed to convert the DC signal from the user's device into the correct logic level used by the processor. Some functions of typical input devices for this series and the 1771-IQC module include proximity switches, select switches, limit switches, push button switches, and float switches. Dc input modules Each module has a variety of input terminals and is compatible with the current chassis, including 1171-A1B, A2B, A3B, A3B1, A4B, AM1, and AM2 chassis. It has 8 input image bits and is addressable with ½ slot, 1 slot, and 2 slot.

The Allen-Bradley 1771-IQC digital input module features input filtering to help limit the effects of voltage transients caused by electronic noise or contact rebound. If not filtered, voltage transients may produce false data. The other components of the 1771-IQC module are protected from possible electrical transient damage by photoelectric isolation, including the module logic circuit, backplane circuit and the entire system. However, some modules in the Bulletin 1771 product line allow users to set input filter time jumpers according to specific module specifications. In addition, the module is compatible with the replaced chassis family, including the 1771-A1, 1771-A2 and 1771-A4 chassis. However, it does not require conditional module placement.
