1746-NI8 输入模块是艾伦-布拉德利 SLC 500 系列的模拟输入模块。该模拟输入模块具有 8 个输入通道,可用于连接多达 8 个采用电压或电流电源运行的不同模拟传感器。1746-NI8 模拟输入模块从这些传感器接收模拟数据,这些数据经过数字转换并存储在其图像表中,整个 SLC 500 系统中的所有模块化 SLC 500 处理器和所有固定 SLC 500 处理器都可以访问这些数据。1746-NI8 输入模块是单插槽模块,支持 1 类配置和 3 类配置。1 类配置使用 8 个输入字和 8 个输出字,而 3 类配置使用 16 个输入字和 12 个输出字。一些 SLC 产品线使用 3 类配置,但固定 SLC 设备仅支持 1 类配置。
箱变测控系统是风力/光伏发电系统中变电的一个重要部分,箱变测控系统主要由箱式变压器、箱变测控装置、辅助通信线路、综自系统和电源部分组成。变测控系统能有效解决因箱变距离监控室远且分散,1746-NI8 模拟输入模块 升压站系统无法实现对箱变监视和控制的问题。
箱变测控系统主要用于箱变低压侧的模拟量采集、非电量保护、远方控制和通讯功能。其主要功能是实现升压站对箱变的远程管理和自动化监控, 满足发电场箱变的 “无人值班, 少人值守”1746-NI8 模拟输入模块 的运行管理方式, 从而也为减少现场维护的工作量以及由此带来的人身安全隐患做出了较大贡献。

1746-NI8 模拟输入模块
Allen Bradley 1756-TBNH is a detachable terminal block (RTB) for the 1756 I/O module. It is an I/O module accessory and must be ordered separately. The 1756-TBNH can flexibly interconnect 1756 I/O modules and industrial factory wiring. It is inserted in front of the I/O module.
The 1756-TBNH detachable terminal block is a 20 position NEMA screw clamp. It has a screw torque of 1.36 Nm and a maximum screwdriver width of 8 millimeters (5/16 inches). It measures 5.51 x 4.41 x 5.71 inches in size. Weighing 0.3 pounds. When wiring, it is necessary to use solid or stranded copper wire of 0.33-2.1 millimeters ^ 2 (22-14 AWG) with a rated temperature of 90 ° C (194 ° F) or higher and a maximum insulation layer of 1.2 millimeters (3/64 inches). Do not connect more than two conductors on any single terminal.
Each ControlLogix I/O module is installed on any ControlLogix chassis and requires a removable terminal block (RTB) to connect all field side wiring. Each I/O module has many applications, from high-speed digital processing to process control. In the ControlLogix architecture, input and output states are shared between multiple controllers in the same or different chassis using producer consumer technology. 1756-TBNH RTB is suitable for clean and dry industrial environments with working temperatures ranging from 0 to 60 ° C and working impacts of 30g.
