I apologize for what may be a silly question. However, I would like to make sure that I have correctly connected the digital input on the TRB140.
I would like to ask if the following connection is correct.
That is, if nothing else is needed, no pull-up resistor, etc. I am concerned with signaling the closing/opening of a dry contact - A dry contact relay. I think the connection is fine. And that the fault is more likely to be in the device that switches the contact. Which, once in a while, closes and opens the monitored contact for no reason within a few minutes.
Thank you very much
Filip
Thank you for your inquiry. Your request is currently under review, and we’ll provide you with an update as soon as possible once the wiring details are fully verified.
If pin 3 is configured as a digital input via Services → Input/Output → Status, then your wiring setup is correct. However, if it is currently set as Output (which is usually set by default), please change it to Configurable input for proper operation.
