Wiring method of time relay of blister packaging machine

The time relay is a very important component in the electrical control system. Generally, there are two types of power-on delay and power-off delay. From the principle of action, there are electronic, mechanical and so on. The electronic type is to use the principle of capacitor charging and discharging and then cooperate with electronic components to realize the delay action. There are many mechanical styles, and there are air bags using air bags and springs.
