How to change the Triconex system AO card to a passive output? Thank you! ! ! ! ! ! ! ! ! ! !
I’ve never heard of this system. . . Can’t it be changed once you enter the configuration interface?
Congisen is the same company as Foxboro. . . . . .
Haven’t heard of this brand; for Yokogawa models, it’s fine as long as the wiring on the card is adjusted
If that doesn’t work, use an active output to the relay, and then use the passive output of the relay to connect to your instrument~ Would that work?
It is possible to modify the wiring at the safety barrier and with the card components, as well as to change active components to passive ones

I think a barrier is the only option. It’s possible. But I think the signal beyond the barrier is still active. I don’t know why the original poster wanted to change it to passive
AO changed to passive? I’ve never heard of it. How can it be used if it’s called “no connection”? How can devices be controlled with it?
Why change it to passive on the same floor as AO? What’s the use? I’ve only heard that AI requires something passive.
OP, do you really have to use the analog signal from the driver locator as the input signal for the digital display? A few days ago, a post asked how to achieve remote DCS monitoring when an on-site digital display unit does not have an analog output function I thought of answering that way at the time, but then I realized that in DCS systems, AO cards are generally used to control regulators (valves). The manufacturer’s documentation does not mention this usage, and I hadn’t tried it myself either, so I didn’t say anything. The other one doesn’t seem standard. Today, I saw a similar question again, but the original poster did take my previous questions into consideration. If it’s really as I said, I suggest you try a different approach. If it is necessary, apply this signal to a precision resistor of 250Ω and use a voltage signal ranging from 1 to 5V, or convert it into a current signal via a safety barrier; this approach is relatively standard. The resistor can be connected to the terminals of the digital display or the safety barrier, which also results in a neater and more organized setup.
