Allen-Bradley 1747-KE是一个接口模块。该模块是SLC 500产品系列的一部分，主要用于通过该模块的嵌入式通信接口实现DH-485和DF1连接。它有一个支持DF1协议的9针Sub-D连接器和一个支持DH-485协议的RJ-45端口。它还有一个(1)9针Sub-D连接器作为模块的配置端口。

1747- ke是一个单槽位模块，安装在1747机箱上。它带有单独的端口隔离，如背板到配置端口之间的500伏直流;背板到DF1接口之间的直流电压为500v, CONFIG到DF1接口之间的直流电压为500v。只有DH-485端口未隔离。它具有c-UL-us, CE和C-Tick认证。它被批准用于第2类，A, B, C或D组的应用领域。

1747-KE可配置RS-232 / RS-423 / RS-422和RS-485。根据通信长度的不同，数据传输速率也不同。端口支持的数据传输速率为300- 19200kbps, RS-232支持的最大电缆距离为15米;60-1230米为RS-423;1230米适用于RS-422和RS-485。一般情况下，电缆长度越大，波特率或传输速率越小。

1747-KE内置了LED指示灯来显示模块的运行状态。具有ACT、485、CFG、DF1、FAULT、BA LOW、H/D、F /D等指示灯。它还带有沿内部电路的嵌入式跳线，用于设置CONFIG端口(JW1)的通信接口;DF1端口(JW2)和接口的功能和模式(JW4)。

1747-KE 接口模块 配置端口

Allen-Bradley 1747-KE is a DH-485/RS-232C interface module that provides connectivity to DH-485 networks and DF1 enabled devices. The module's DF1 port can be configured to function as an RS-232/422 device. It can also be configured as RS-422 and RS-485 devices. Allen-Bradley 1747-KE has 8 LED indicators. Indicators are located on the front panel of the module. These indicators are used for module diagnostics and operating interfaces. The module can be connected to most types of dial-up networks or direct modem connections. The Allen-Bradley 1747-KE had an operating shock of 30 g and a vibration of 2.5 g at 57-2000 Hz. The relative humidity of the module ranges from 5% to 95%, without condensation. This module working temperature of 0 to 60 a ° C (32-140 - a ° F), storage temperature was minus 40 ° C to 85 ° C (to 40 ° F to 185 ° F). The supported modems are Manual modem, DTE Controlled Answer, Auto Answer, and Direct Connect. The 1747-KE module requires 5V DC and 24V DC power supplies from the SLC backplane. Module power consumption should be considered when designing the SLC 500 system. After the power supply is completely cut off (about 10 seconds), install or remove the 1747-KE module from the chassis.

Allen-Bradley 1747-KE is an interface module. The module is part of the SLC 500 product family and is primarily used for DH-485 and DF1 connectivity through the module's embedded communication interface. It has a 9-pin Sub-D connector that supports the DF1 protocol and an RJ-45 port that supports the DH-485 protocol. It also has a (1) 9-pin Sub-D connector as a configuration port for the module.

The 1747-KE is a single-slot module that is installed in the 1747 chassis. It comes with separate port isolation, such as 500 volts DC between the backplane and the configuration port; The DC voltage between the backplane and DF1 port is 500v, and the DC voltage between the CONFIG and DF1 port is 500v. Only DH-485 ports are not isolated. It has c-UL-us, CE and C-Tick certifications. It is approved for use in Category 2, Group A, B, C or D applications.

The 1747-KE can be configured with RS-232 / RS-423 / RS-422 and RS-485. Depending on the length of the communication, the data transmission rate is also different. The data transmission rate supported by the port is 300-19200 KBPS, and the maximum cable distance supported by the RS-232 is 15 meters. 60-1230 meters is RS-423; 1230 m is suitable for RS-422 and RS-485. In general, the larger the cable length, the smaller the baud rate or transmission rate.

The 1747-KE has a built-in LED indicator to show the operating status of the module. It has indicators such as ACT, 485, CFG, DF1, FAULT, BA LOW, H/D, and F /D. It also has an embedded jumper along the internal circuit for setting up the communication interface of the CONFIG port (JW1); DF1 port (JW2) and interface function and mode (JW4).
