Hi there,
I have two questions. Well, is there how to monitor my output in my PLC without a sensor? For example, if I energize my VALVE (24VDC) throughout my PLC, is there a way to know if my solenoid was energized? (Without a magnetic sensor).
Second:
I'm currently working in a project where I have to use a transformer from 380 VAC to 220VAC. What is the best practice in this case, i. e., Have I to put my transformer in my control panel enclosure? Have I to energize my transformer and after that put my 3 phases in my disconnect switch and my PE direct connect in my terminal block and after in my main circuit breaker?
Any help will be very appreciated.
