AB模块 1756-L71S电源

1、可靠性高
PLC的MTBF一般在40000～50000h以上，西门子、ABB、松下等微小型PLC可达10万h以上，而 且均有完善的自诊断功能，判断故障迅速，便于维护。

2、模块化组合灵活
可编程控制器是系列化产品，通常采用模块结构来完成不同的任务组合。I/O从8～8192点， 有多种机型、多种功能模板可灵活组合，结构形式也是多样的。

3、功能强
PLC应用微电子技术和微计算机，简单型式都具有逻辑、定时、计数等顺序控制功能。基本 型式再加上模拟I/O、基本算术运算、通信能力等。复杂型式除了具有基本型式的功能外，还具有扩展的计算能力、多级终端机制、智能I/O、PID调节、过程监视、网络通信能力、远程I/O、多处理器和高速数据处理能力。

1, high reliability
PLC MTBF is generally more than 40,000 ~ 50000h, Siemens, ABB, Panasonic and other micro-small PLC can reach more than 100,000 h, and have a perfect self-diagnosis function, judge the fault quickly, easy to maintain.

2, modular combination is flexible
Programmable controllers are serialized products, usually using a modular structure to complete different combinations of tasks. I/O from 8 to 8192 points, there are a variety of models, a variety of functional templates can be flexibly combined, the structure is also diverse.

3, strong function
PLC application of microelectronics technology and microcomputer, simple types have logic, timing, counting and other sequence control functions. Basic types plus analog I/O, basic arithmetic operations, communication capabilities, etc. In addition to the functions of the basic model, the complex model also has extended computing power, multi-level terminal mechanisms, intelligent I/O, PID regulation, process monitoring, network communication capabilities, remote I/O, multiprocessors, and high-speed data processing capabilities.
