Help, there’s an issue with the do output
Thread Content
Is the DCS DO output dry contact or wet contact? Is it equipped with a 24-volt supply? After output, could you please provide a diagram showing how the electricity flows in the circuit? Thank you to anyone who can help!
Go to the electrical department; ask them to tell you whether what you need is active or passive. If it requires an active component, then connect it properly. I’m not sure about the details; I hope someone more knowledgeable can answer your question
Whether the DO point is dry or wet depends on the specific circumstances; it cannot be determined simply. In electrical systems where components are connected to control circuits, they are mostly dry, while those related to control solenoids and similar components are mostly wet
They are generally dry contacts, depending mainly on whether power is connected to them……
To connect to an electrical circuit, isolation using a relay is necessary. As for diagrams… there are many available online; look up diagrams related to the isolation of low-voltage and high-voltage circuits by searching on Baidu
