Active contacts?
Active contacts?
(OP)
Has anyone heard the term active contact before? is this the opposite to dry contacts? We have an auma actuator and the remote open and remote close signals are powered by 24VDC from the DCS to me these are dry contacts. Our client is saying that these two signals require a relay and they are active contacts. has anyone heard this before?
Thanks
Thanks





RE: Active contacts?
There is also a term used in machine safety circuits called "positive operation" contacts, which I have also seen called "active operation" which I think is a misnomer, because there IS a stated definition for "positive operation" in safety standards.
