1794-ACNR15 是一个冗余控制网通信模块

Allen-Bradley 1794-ACNR15是一个冗余控制网通信模块。该模块是Flex I/O产品系列的一个组件产品，用于在各种应用程序和行业中实现分布式I/O。

1794-ACNR15支持ControlNet协议。它可以通过连接到控制网中继连接来实现冗余控制网拓扑。1794-ACNR15有2个控制网通信端口，每个端口连接到单独的中继。当一条控制网络中继故障时，数据自动路由到第二条控制网络中继。

1794-ACNR15支持5Mbps的控制网传输速度，可以安装任意组合的8个Flex I/O模块。

该模块需要外部电源才能工作。可接受的电源电压范围为19.2…31.2V DC，电流为400ma。标称电源电压为24VDC。电源连接使用0.33…2.5平方。毫米(22…12AWG)实心或绞合铜线，绝缘等级为75°C(167°F)或更高，最大绝缘厚度为1.2 mm(3/ 64英寸)。对于双线连接，使用0.33…1.3平方。毫米(22…16AWG)不混合的实心或绞合铜线，绝缘等级为75°C(167°F)或更高，绝缘厚度为1.2 mm(3/64英寸)。

1794-ACNR15有LED指示灯，可以显示模块的工作状态。这些LED指示灯包括I/O状态、控制网口A状态的Comm A和控制网口B状态的Comm B。这些LED状态指示灯是有用的监控和故障排除辅助，传达特定的信息。

1794-ACNR15可以使用DIN导轨或墙壁安装，扭矩要求为7磅-英寸。该模块的尺寸为87x 94x 69毫米，重约220克(7.76盎司)。1794-ACNR15具有T4温度代码，并在开放式外壳类型额定值下在19.2伏直流下散发3.4 W的热量。它的工作温度范围为-25至55摄氏度(-13至131华氏度)，非冷凝相对湿度为5-95%。它的最大工作冲击率为30G，在非工作模式下可以达到50G，在10到500赫兹的工作振动为5.0G。

Allen-Bradley 1794-ACNR15 is a redundant control network communication module. This module is a component product of the Flex I/O product family for implementing distributed I/O in a variety of applications and industries.

1794-ACNR15 supports the ControlNet protocol. It can implement redundant control network topology by connecting to the control network relay connection. The 1794-ACNR15 has two control network communication ports, each connected to a separate trunk. When one control network relay fails, data is automatically routed to the second control network relay.

The 1794-ACNR15 supports a 5Mbps control network transfer speed and can install any combination of eight Flex I/O modules.

The module requires an external power supply to work. The acceptable supply voltage range is 19.2... 31.2V DC, current is 400ma. The nominal supply voltage is 24VDC. Power connection using 0.33... Two and a half square. Mm (22... 12AWG) solid or stranded copper wire with an insulation class of 75°C(167°F) or higher and a maximum insulation thickness of 1.2 mm(3/64 inch). For two-wire connections, use 0.33... 1.3 square. Mm (22... 16AWG) unmixed solid or stranded copper wire with an insulation class of 75°C(167°F) or higher and an insulation thickness of 1.2 mm(3/64 inch).

The 1794-ACNR15 has an LED indicator to show the working status of the module. These leds include I/O status, Comm A of control network port A, and Comm B of control network port B. These LED status indicators are useful monitoring and troubleshooting AIDS that convey specific information.

The 1794-ACNR15 can be mounted using DIN rails or walls and has a torque requirement of 7 pound-inches. The module measures 87x 94x 69mm and weighs about 220g (7.76 oz). The 1794-ACNR15 has a T4 temperature code and emits 3.4 W of heat at 19.2 volts DC at an open housing type rating. It operates in a temperature range of -25 to 55 degrees Celsius (-13 to 131 degrees Fahrenheit) and a non-condensing relative humidity of 5-95%. It has a maximum operating shock rate of 30G, can reach 50G in non-operating mode, and has an operating vibration of 5.0G at 10 to 500 Hz.
