Except for the active contacts which are directly powered by external 220VAC electricity, are other functions such as analog input and output powered by the terminal block at 24VDC? Then, similar to digital output, the passive contacts are powered by a 24VDC terminal block through solenoids, while the active contacts are powered by 220VAC via solenoids in the control cabinet. Does this not cause a conflict with the 24V from the terminal block?

The wrong place to post this; go to the Public Works Discussion Area – Control System Technology Discussion Area instead. The way it’s written is not professional at all; definitely, the vast majority of 24V systems are powered by DCS
