     For analog design which is my main area of work I rarely use the autorouter, as layout and the track routes are important elements of the design. But if you use the autorouter use it in steps and ...

    Check these out https://uk.rs-online.com/web/p/iec-filters/7823970/ I think they are an IEC C8 connector that the C7 (confusing!) plugs into. This will provide a range to select fromhttps://uk.rs-o...

    SW1 is wrong, when not connecting to the relay it will power the Tens unit continuously, just remove the link between the two poles or use the single pole switch I drew earlier.Unless my sums scrib...

    The switch is in my edited diagram of yours posted above. Just a switch in series with the Tens power unit. If you do not have a switch the Tens will be powered all of the time when not generating ...

    Yes, but do consider the start up and ending situations, you may require a disable switch? and if not built in a diode across the coil. You could also add the bridge rectifier into the circuit so ...

    On my system it is as below, but the PCB window must be active.  

  • Boss . commented,

    Well, that confirms it is 120V DC.... I suggest you examine relays in the 110V to 120V operating range.Non-Latching Relays | RS Components (rs-online.com) select some options on coil voltage then s...

    A Happy New Year to you. With the PCB view active, go to the menubar and select 3D - 3D view.

  • Boss . commented,

    Hmmm, well from how you describe your customers' knowledge I would first question the 120VDC output from the generator, are you sure it's not 12.0VDC? 0V is both precise and vague, in the sense are...

    Hi Richard, I kept my original reply brief to try get more info from you.Based on your circuit above the issues requiring to resolve are: Relays as Brad says have very wide ranges of operation whic...
