How can the signals of magnetic switches of four cylinders and eight sensors be converted into signals of a group of injection molding machines?

1. It is very convenient to use TPC8-8TD timing program controller. Your eight magnetic switches can be directly connected to the input end of the controller, and the 24V solenoid valve can be directly connected to the control output end for direct control.

2. Connection of magnetic switches: The magnetic switches should be connected to the control inputs respectively, and the series connection is incorrect.

3. Set the required control function in the function setting table to realize the required control function.

4. Suggestion: You can use several magnetic switches as needed, and only use magnetic switches in key positions. The position control of magnetic switch or the combination of local control and timing control can be adopted to realize the overall automatic control, and the magnetic switch can be omitted. If the total number of magnetic switches and start-stop switches is less than or equal to four, it is more economical to use TPC4-4 timing program controller to control four solenoid valves of four cylinders, only 300 yuan.
