PLC接线端罗克韦尔PLC模块 AB 1756-TBNH

1756-TBNH可移动端子座是一个20位NEMA螺丝夹。它有一个1.36 Nm的螺丝扭矩和一个8毫米(5/16英寸)的最大螺丝刀宽度。它的尺寸为5.51 x 4.41 x 5.71英寸。重0.3磅。在任何一个端子上，不要连接两个以上的导体。

每个ControlLogix I/O模块安装在任何ControlLogix机箱上，并需要一个可移动的终端块(RTB)来连接所有现场侧接线。每个I/O模块都有许多应用，从高速数字处理到过程控制。在ControlLogix架构中，使用生产者-消费者技术在相同或不同机箱中的多个控制器之间共享输入和输出状态。1756-TBNH RTB适用于清洁干燥的工业环境，工作温度为0-60°C，工作冲击为30g。

1756-TBNH 是由 Allen-Bradley/Rockwell Automation 在 ControlLogix 系列中制造的可拆卸接线端子或 RTB 模块2。这个模块主要用于连接 1756 I/O 模块和工业厂房布线，可以灵活地互连 1756 I/O 模块和工业厂房布线。

1756-TBNH 模块的特点包括：它可以同时使用 20 根导线。连接到 1756-TBNH 可拆卸接线端子的电线应全部相同尺寸，并且它们应全部为实心线或所有绞合线，因为该块不支持实心线和绞合线的混合。1756-TBNH 可拆卸接线端子是一个 20 位 NEMA 螺钉夹，具有 1.36 Nm 的螺丝扭矩和 8 毫米（5/16 英寸）的较好螺丝刀宽度。它的尺寸为 5.51 x 4.41 x 5.71 英寸，重0.3磅。

此外，1756-TBNH 模块还适用于工作温度为 0-60 °C 和 30g 工作冲击的清洁干燥工业环境。在使用过程中，必须注意一些接线规则，例如，每个 ControlLogix I/O 模块都安装在任何 ControlLogix 机箱上，并且需要一个可拆卸的接线端子（RTB）来连接所有现场侧接线。

The 1756-TBNH Removable 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 mm (5/16 inch). It measures 5.51 x 4.41 x 5.71 inches. It weighs 0.3 lbs. Do not connect more than two conductors to any one terminal.

Each ControlLogix I/O module mounts 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 state is shared between multiple controllers in the same or different chassis using producer-consumer technology.1756-TBNH RTBs are suitable for clean and dry industrial environments with operating temperatures from 0-60°C and operating shocks up to 30 g. The 1756-TBNH RTBs are designed for use in a wide range of applications.

The 1756-TBNH is a removable terminal block or RTB module manufactured by Allen-Bradley/Rockwell Automation in the ControlLogix family.2 This module is primarily used for connecting 1756 I/O modules to industrial plant wiring and provides flexibility in interconnecting 1756 I/O modules to industrial plant wiring.

Features of the 1756-TBNH module include the fact that it can utilize up to 20 wires simultaneously. The wires connected to the 1756-TBNH Removable Terminal Block should all be the same size and they should all be solid or all stranded wires as the block does not support a mix of solid and stranded wires.The 1756-TBNH Removable Terminal Block is a 20-position NEMA screw clamp with 1.36 Nm of screw torque and a good screwdriver width of 8 mm (5/16 in.). It measures 5.51 x 4.41 x 5.71 inches and weighs 0.3 lbs.

In addition, the 1756-TBNH module is suitable for use in clean, dry industrial environments with operating temperatures of 0-60 °C and 30 g of working shock. There are some wiring rules that must be observed during use, such as the fact that each ControlLogix I/O module is mounted on any ControlLogix chassis and requires a removable terminal block (RTB) for all field-side wiring.
