Old hard to find cord`s circuit?
So at my school we still use old old programmable relays. The Crouzet Millenium 2. The problem is that we are plugging in and out the cords each day which leads to as you can think, them to stop working. My teacher can not find them and I am sure the school does not have the 100 ish dollars to drop on one cord. It is part public school so its not the richest. If my teacher had at least the whole schematic for the cord, then he can make his own cords to at least let us us them without having to upload 50 thousand times to try and get a response from the things brain. The cords model number is 88950102 if this helps
