A 220V contactor, an intermediate relay, an electrode point pressure gauge, and a physical line diagram
It's very simple. Say, you'll answer!Zero line intermediate relay (8 feet of MY2NJ, 7 feet, 14 feet MY4NJ, 13 feet) - and then connected to the contactor coil at any end.Phase line contact voltage meter input (usually red line) - and then connected to the intermediate relay (8 feet MY2NJ, 8 feet, 14 feet of MY4NJ 14 feet) - and then to the middle relay 1 feetThe middle relay 3 feet are connected to the other end of the contactor coil
If you don't give a cent, tell me at least how you want to control it Pressure gauge control relay, relay control contactor
A 220V contactor, an intermediate relay, an electrode point pressure gauge, and a physical line diagram are as follows:Turn left and turn right |This method is the pressure drop, the NC normally closed contacts closed, relay pull in, contactor also pull in, the load will workL is FireWire, N is zero line, 13 and 14 are relay coils, A1 and A2 are contactor coils, and 3 red ones are power lines.
