NPN Output 20 Points Micro PLC


AF-20MT-D2 DC12/24V, 12points DC input 8 points transistor output (equivalent NPN) micro PLC
PLC mainly has two types of structure: integral type and modular type.
The average price of each I/O point of the integrated PLC is cheaper than that of the modular type, and the volume is relatively small. It is generally used in a small control system with a fixed system process; while the function of the modular PLC is flexible and convenient. The choice of I/O points, the ratio of the number of input points to the number of output points, and the type of I/O modules are large, and the maintenance is convenient, generally in a more complicated control system.
