Help me figure out how to connect this valve – just the actuation is needed, no feedback signal required
Firstly, this valve requires a 220V power supply; it is a on/off switch valve that only needs the positive and negative terminals to be connected. These two terminals are used to control the coil of the contactor; connect them to a voltage level that matches the voltage required by the coil of the contactor.
Do I still need to add a relay?
It’s best not to make any changes; it’s good to have a feedback signal. It’s just a suggestion; if changes are truly necessary, they can only be made with the approval of the relevant authorities. If problems do arise as a result of this, responsibility must be held.
