Valve actuators / Yokogawa ADV869

[stevdan]

Hello guys,
I have to send some Digital output from DCS ( ADV869 ) to control a valve open / close.
The valve actuator diagram is Emerson M2cp.

I know ADV869 has transistors contract as output, I was thinking to put sthg between the ADV869 and the actuator to handle the 115V..

any suggestions please

Thank you

Your link seems to be broken.

At any rate it is unlikely that a transistor output could handle the voltage or current that a valve actuator would require. You need to determine those two values, and use the PLC output to control a relay or contactor that in turn controls the power that actually operates the valve.
