Hi all, I'm a 2nd year apprentice and this question is really more for my own understanding. I understand HOW an electromagnetic relay works. I know that control and power circuits are electrically isolated. I understand the design config of core, winding, applied I/P voltage, magnetic field, max voltage/current at contacts, max/min pull in and fall out. I know that by design you can have differing coil and contact sources (DC in/ AC out), as well as differing coil and contact rating voltage (24VDC coil and 125VDC power out). It's this last bit I don't understand. How are we able to get 125VDC to our contactor when A) our relay circuits are isolated, and B) our supply voltage is only 24VDC? is it just the result of current flow in the second circuit (power); is it contact design (air gap, materials).. I'm sure I'm making it harder than it has to be, since operational data is provided with the relay. I would love a real explanation on what happens to allow this to ensure I have the right handle on theory. Thank you in advance.
