Seeking help regarding the model of the central control card
Thread Content
I need help – what are the functions of the XP351, XP366, and XP367 cards shown in the image, and what are the differences in their wiring? I’ve never seen these model cards on the cabinets in the factory before. Please ask someone who understands to explain it. Thank you

One more question: Is the digital signal input card for XP366 the DI point signals? If that’s the case, then why isn’t it called a digital signal input card? If it’s not, could you please explain? For example, what type of instruments output digital signals? Haha! I’m a beginner who has just started working with DCS; please forgive me if my questions are stupid: lol
I’m also a beginner with DCS; the XP351 is a spare part that was introduced in recent years.
