PLC Programmable Logic Controller features which

High reliability is the key to the performance of electrical control equipment. Plc logic controllers LSI due to the use of modern technology, strict production plc analog input output module process, the internal circuit to take the advanced anti-jamming technology with high reliability. For example, the production of F series Mitsubishi PLC MTBF of up to 300,000 hours. Some use redundant PLC CPU MTBF working time is longer. PLC of the machine outside the circuit, constitute a control system using PLC, and the same scale relay contactor systems, electrical wiring and switch contacts have been reduced to hundreds or even thousands of times, the fault will be greatly reduced. In addition, Plc logic Programmable Input Module controllers with hardware fault self-test function, failure to give timely warning information. In the application, the application are also incorporated into the self-diagnostic program peripheral devices, the system in addition to the PLC circuits and equipment also gained self-diagnostic protection. Thus, the entire system has high reliability is not surprising.
