Digital Input 20 Points Micro PLC


AF-20MT-E2 DC12/24V, 12points DC input 8 points transistor output (equivalent NPN) micro PLC
The choice of PLC should be considered from the aspects of PLC model, capacity, I/O module, power module, special function module, communication networking capability and so on. The basic principle of PLC model selection is to strive for the best performance-price ratio under the premise of satisfying the functional requirements and ensuring reliability and maintenance. When selecting, it should mainly consider the reasonable structure type, the choice of installation method, the corresponding functional requirements, the response speed requirement, the system reliability requirements, and the uniformity of the model.
