I’m sorry, but based on the information provided, it is not possible to determine whether the DI and DO signals are input or output power sources. Because the DI and DO signals can be used for input or output in DCS systems, their specific use depends on the system design and application requirements. Please provide more detailed information or consult the equipment manufacturer for a more accurate answer. .

Input/output is applicable to DCS. It is the input/output power supply; it is necessary to consider who will provide the power. If DI and DO are passive contacts powered by a source outside the DCS, it is the input power supply ； The power supply powered by DCS is the output power supply.
The table shows the DCS output power supply.
I is input, O is output
