We are having a problem with our AP-24x printer. When the vacuum motor spins up we get a 60 hz buzz into the DC drivers for the forcers and the stencle wiper. We also indicate a main power drop from 115 vac to 80 vac. The vacuum motor checks out good

Relay Coil Impedence

You shouldn't be worrying about "impedance" on a DC relay. Just measure the resistance with a Voltmeter/Ohmmeter. If you need to know the current draw, it will be 24/resistance The impedance of an AC relay changes as the armature moves from the "off
