IC695CRU320 High reliability and strong anti-interference ability

IC695CRU320 has outstanding advantages such as high reliability and strong anti-interference ability, and is widely used in the field of industrial control, becoming one of the main pillars of modern industrial automation. In the design of PLC control systems, it is common to encounter issues such as tight I/O point resources and conflicting cost-effectiveness. Some controlled devices require manual and automatic working modes, and there are many control buttons for the manual part; In some automatic production lines, there are too many stroke switches for position detection or outputs for system working status indication, which can greatly increase the occupied I/O points.

IC695CRU320 is generally solved by adding expansion modules, but PLC I/O points are expensive and there are limitations on the number of expansion modules and I/O points. For example, SIEMENS CPU 226 has a maximum expansion module number of 7, with a maximum expansion of 168 digital I/O points or 35 analog I/O points. If the CPU is increased at this time, it will inevitably greatly reduce the cost-effectiveness of the system. In this case, expanding the number of I/O points has significant practical significance.
