数据采集、手持终端、网络安全、消费电子等领域，具有低功耗、高集成度及高性价比等特点。其中龙芯IA32位处理器和龙芯1C 64位处理器稳定工作在266~300MHz，龙芯1B处理器是一款轻量级32位芯片。龙芯1D处理器是超声波热表、水表和气表的芯片。2015年，新一代北斗导航卫星搭载着我国自主研制的龙芯1E和1F芯片，这两颗芯片主要用于完成星间链路的数据处理任务一。

输出单元也是PLC与被控设备之间的连接部件，它的作用是把PLC的输出信号传送给被控设备，即将中央处理器送出的弱电信号转换成电平信号，驱动被控设备的执行元件。输出的类型有继电器输出、晶体管输出、晶闸门输出。

PLC除上述几部分外，根据机型的不同还有多种外部设备，其作用是帮助编程、实现监控以及网络通信。常用的外部设备有编程器、打印机、盒式磁带录音机、计算机等。

Data acquisition, handheld terminals, network security, consumer electronics and other fields, with low power consumption, high integration and cost-effective characteristics. Among them, Loongson IA32-bit processor and Loongson 1C 64-bit processor work stably at 266~300MHz, and Loongson 1B processor is a lightweight 32-bit chip. The Loongson 1D processor is a chip for ultrasonic heat meters, water meters and gas meters. In 2015, the new generation of Beidou navigation satellites were equipped with the Longson 1E and 1F chips independently developed by China, which are mainly used to complete the data processing task of inter-satellite links.

The output unit is also the connection part between the PLC and the controlled device, its role is to transmit the output signal of the PLC to the controlled device, that is, the weak current signal sent by the central processor is converted into a level signal, and the executive element of the controlled device is driven. The output types are relay output, transistor output, and gate output.

In addition to the above parts of the PLC, there are a variety of external devices according to the different models, whose role is to help programming, monitoring and network communication. Commonly used external devices are programmers, printers, cassette tape recorders, computers, etc.
