Unswitched and switched power supply
The unswitched 24 V power supply (also known as non-switched) on X1.2 and X1.4 provides

X1.1 and X1.5 supplies power for the two digital outputs (DI0 and DI1).
For a complete explanation of the unswitched and switched 24 V supplies and their
limitations, please read the FAQ at the following link:
