5SHX0660F0002 PLC system equipment

The main purpose is to control the external system. This system may be a single machine, a group of machines or a production process. Different models of PLC have different scope of application. When 5SHX0660F0002 water consumption is reduced and the water supply pressure is greater than the set value, the output frequency of the frequency converter is reduced, the pump speed decreases, and when the output frequency of the frequency converter reaches the minimum value (30hz), after a delay of 20s, a command is issued to reduce one industrial frequency pump, and the other pumps in turn.

5SHX0660F0002 According to the requirements of the production process, analyze the complexity of the controlled object, carry out the statistics of the number of I/O points and the type of I/O points (digital, analog, etc.), and make a list. Estimate the memory capacity appropriately, and determine the appropriate models (small, medium, and large shaped machines) that leave a margin without wasting resources. And in conjunction with the market situation, examine the PLC manufacturer’s products and their after-sales service, technical support, network communications and other comprehensive situation, select the PLC model with better price performance.
