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

Switched out the mech. relay on the board loader, no change. Same behavior. Could not find a mech. relay on the printer... SMEMA wiring appears go directly to a PCB. And it is at that point that I run out of talent. If the machine weren't dedicate

I Changed old parts to New Parts for: All 5 Magnetic Contactors, Circuit Breaker/Protector 1, I/O Switch housing + contact blocks, both 12v and 110v relays. Still CP40 contactors won't engage after I/O Switch is pressed, G9D-301 Safety Relay Power Le

I'm working on a project that requires that I analyze a signal from the parallel port of my computer and use it to turn on relays. There are about 19 relays to control, and I designed all the gates to get each one on, but there is a problem with keep

Thanks for the informative posting.. When I power up the machine this is what I get.. 1. The movable cutter does not actuate the cutter knifes. (The head still jogs 360 and the movable cutter moves in the linear axis but the c&c motor does not act

pls check at rear side is there any relay spark or else check the connection between the monitor and the control card

Yes, it was a relay that control lid up or down.it fixed now. thanks
