The standard output voltages on cards are24Vdc. But it depends that what are configurations and supply voltages for cards.

Variety of output voltages can be supplied based on Digital Output Modules used and the termination boards used with them.

24 VDC is commonly used with a maximum load of125 mA. Other modules can withstand up to500 mA. Others can provide relay outputs when combined wth the suitable termination boards. Termination boards can be used from Yokogawa or from other manufacturers that are manufacturing termination boards compatible ith Yokogawa cabling system like P+F, Phoenix Weidmuller and MTL.

Dear Hamza , please specify which Yokogawa DCS model and the exact card you're talking about , generally speaking older DCS could only provide24 VDC while newer models can provide220 VAC along with the standard24 VDC.
