GE lJR6DH是一款局域网接线端子板，设计用于531X系列替换板。通用电气公司的驱动器和激励器可以在其机柜中接受此板。当安装板时，它为外部设备和控制驱动器之间提供接口系统。板上的八个可配置的控制输入插头在安装时提供给驱动器，额定输入电压范围为2至240 V交流电源和DC电源都可以被接受。板产生的信号可通过局域网终端、驱动控制板和NTB端子板进行传输。

It is a LAN terminal board designed for use with the 531X series replacement board. General Electric's drives and actuators can accept this board in their cabinets. When installing the board, it provides an interface system between external devices and control drivers. The eight configurable control input plugs on the board are provided to the driver during installation, with a rated input voltage range of 2 to 240 V for both AC and DC power sources. The signals generated by the board can be transmitted through local area network terminals, driver control boards, and NTB terminal boards.
