Motor operation status feedback
Thread Content
I have a question: For the same motor, I need two status signals indicating its operation – one of these signals is to be sent to one DCS, and the other signal to another DCS. Should they be connected to the same passive point electrically, or separately? If connected to the same point, will different DCS systems affect each other’s voltages? Thank you~~~
Connect them separately; if there are not enough contacts, use a relay for expansion.
If the DCS units are powered, they will affect each other; therefore, it is necessary to increase the number of contacts on the contactors. If there are not enough contacts, an expansion on the electrical side should be carried out, with outputs for different circuits
Connect them separately: one connection should go to the DCS, and the other to the SIS. The status of the motors on the cabinet side is represented by DI input points, and these points are supplied with 24V power. If connected in parallel, it will combine the power supplies of the DCS and SIS
Connect them separately; otherwise, there will be interference and some unexpected problems may arise
