LM3104 DC24V power supply, ?8 Channels DC24V DI,6 Channels?Transistor DO?PLC
(1) The input/output function modules are complete. One of the biggest advantages of PLC is that for different field signals (such as DC or AC, switching, digital or analog, voltage or current, etc.), there are corresponding templates for industrial devices (such as buttons and switches). , sensor current transmitter, motor starter or control valve, etc.) are directly connected and connected to the CPU motherboard through the bus.
(2) Easy to install. Compared with computer systems, PLC installation does not require a dedicated machine room or strict shielding measures. When you use it, you only need to connect the detection device to the I/O interface terminal of the actuator and PLC correctly, and it can work normally.
(3) The running speed is fast. Since the control of the PLC is controlled by the program, regardless of its reliability or operating speed, the relay logic control cannot be compared.
