1756-TBNH/A   Allen-Bradley 用于1756 I/O模块的可拆卸接线板(RTB)

Allen-Bradley 1756-TBNH是用于1756 I/O模块的可拆卸接线板(RTB)。它是一个I/O模块附件，必须单独订购。1756-TBNH在互连1756 I/O模块和工厂布线方面提供了灵活性。它插入I/O模块的前面。

1756-TBNH可拆卸接线板是一个20位NEMA螺旋夹。它有1.36牛米的螺丝扭矩和8毫米(5/16英寸。)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。对于布线，使用0.33–2.1 〖mm〗^2(22-14 AWG)的实心或绞合铜线，额定温度为90°c(194°f)或更高，直径为1.2毫米(3/64英寸)。)必须使用标准最大绝缘。在任何单个端子上，不要连接超过两根导线。

每个ControlLogix I/O模块可安装在任何ControlLogix机箱上，并需要一个可拆卸的接线板(RTB)来连接所有现场接线。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。

Technical Specifications for 1756-TBNH

The Allen-Bradley 1756-TBNH is a Removable Terminal Block (RTB) for 1756 I/O modules. It is an I/O module accessory and must be ordered separately. The 1756-TBNH provides flexibility in interconnecting 1756 I/O modules and industrial plant wiring. It plugs into the front of the I/O module.

The 1756-TBNH removable terminal block is a 20-position NEMA screw-clamp. It has a 1.36 Nm Screw torque and an 8-mm (5/16 in.) maximum Screwdriver width. It has dimensions of 5.51 x 4.41 x 5.71 in. and weighs 0.3 pounds. For wiring, use 0.33 – 2.1 〖mm〗^2 (22 – 14 AWG) solid or stranded copper wire rated at 90 °C (194 °F) or greater with a 1.2-mm (3/64-in.) gauge maximum insulation must be used. On any single terminal, do not wire more than two conductors.

Every ControlLogix I/O module mounts on any ControlLogix chassis and requires a removable terminal block (RTB) to connect all the field-side wiring. Each I/O module has many applications ranging from high-speed digital processing to process control. In ControlLogix architecture, input and output status is shared among multiple controllers in the same or different chassis using producer-consumer technology. The 1756-TBNH RTB is intended for use in a clean and dry industrial environment with a 0-60 °C operating temperature and a 30g operating shock.
