Allen-Bradley的1794-TB3G Flex I/O终端基础单元是一种终端基础单元模块,安装有面板或DIN导轨,并提供终端I/O接线连接点。它有36个最大输入/输出端子,2个公共端子和2个正电压端子。它有10个机箱接地端子,适用于10A和31.2V直流应用。它通过接地螺丝钳提供I/O终端,终端螺丝扭矩为0.56 x 0.79 Nm (5-7lb-in)。I/O模块通过1794-TB3G连接到I/O总线,它还在5V DC下提供640mA的FLEXBUS电流,最大I/O端子电流为2A。

它的电压/通信终端额定值为125V DC/AC和10A,频率为50-60 Hz,在现场接线端子和FLEXBUS或任何较小的模块之间,使用基本绝缘类型在2121V DC下测试60s,可提供最大50V(连续)电压隔离。1794-TB3G使用0.21 x 1.3 mm2 (24-16 AWG)绞合尺寸铜线,额定温度为75°C(167°F),绝缘为1.2 mm(3/64英寸),整个模块具有T4A和IEC TA温度代码。它在-20至70°C(-40至158°F)的温度范围内不起作用,在5-95%的非冷凝环境相对湿度下存储在工厂指定的-40-85°C(-40-185°F)温度范围内。它可以在30G的操作冲击等级和10-500Hz的5G振动下保持标准功能。

The 1794-TB3G Flex I/O Terminal Base Unit by Allen-Bradley is a terminal base unit module that is installed with a panel or DIN rail and provides terminal I/O wiring connection points. It has 36 maximum input/output terminal points with 2 common terminals and 2 positive voltage terminals. It has 10 Chassis Ground Terminals and is built for uses in 10A and 31.2V DC applications. It provides I/O termination through the Grounded Screw Clamp and has a terminal screw torque of 0.56 x 0.79 Nm (5-7lb-in). The I/O modules are connected to the I/O bus through the 1794-TB3G and it also provides a FLEXBUS current of 640mA at 5V DC with a 2A maximum I/O terminal current.

It has a Voltage/Communication terminal rating of 125V DC/AC and 10A at 50-60 Hz and it delivers a maximum 50V (continuous) voltage isolation using the Basic Insulation Type tested for 60s at 2121V DC between the Field Wiring Terminals and FLEXBUS or any lesser module. The 1794-TB3G uses a 0.21 x 1.3 mm2 (24-16 AWG) stranded size copper wire rated at 75 °C (167 °F) with 1.2 mm (3/64 in) insulation and the whole module is given the T4A and IEC TA temperature codes. It functions without de-rating at a temperature range between -20 and 70 °C (-40 and 158 °F) at 5-95% non-condensing ambient relative humidity is stored at a factory-specified -40-85 °C (-40-185 °F) temperature range. It is built to retain standard functions at an operational shock rating of 30G and a vibration of 5G at 10-500Hz.
