LM3109 220VAC power supply, 24 Channels DC24V DI,16 Channels Relay DO PLC
(1) High reliability. Since PLCs mostly use a single-chip microcomputer, the integration is high, and the corresponding protection circuit and self-diagnosis function improve the reliability of the system.
(2) Programming is easy. PLC programming mostly uses relay control ladder diagrams and command statements, the number of which is much less than the microcomputer instructions. In addition to medium and high-end PLCs, there are only about 16 small PLCs in general. Due to the simplicity of the ladder image, it is easy to master, easy to use, and even requires no computer expertise to program.
(3) Flexible configuration. Since the PLC adopts a modular structure, the user can flexibly change the function and scale of the control system by simply combining, so that it can be applied to any control system.
