IC697MDL653 Positive/Negative Logic Input Module

IC697MDL653 Positive/Negative Logic Input Module

IC697MDL653  The connection between the main unit and the actuator-sensor-interface slaves is made through the AS-I master without additional editing of the communication program. It is very convenient for the engineers that the remote I/O corresponds to the corresponding bit in the image area, which is in line with their programming habits.

IC697MDL653 application of two-wire communication, the system connecting line adopts snap wire piercing structure, the amount of wiring is greatly reduced, and the unique AS-I ladder cable eliminates the possibility of wiring errors, compared with the previous PLC control system can save a lot of cables, and the installation workload is also greatly reduced.

IC697MDL653 Elevator control system from relay control development to PLC plus governor control mode, has experienced a considerable technological leap, the existing products are also shaped, and the performance is quite stable, the basic structure of the existing elevator control system shown in Figure 1. The control center is in the roof machine room, all signals in the shaft and car are transmitted to the control center in the form of point-to-point through a large number of cables.
