Re: 100% Security During Boot 4 Peanuts ! Quad Contacts Option |
The possibility of requiring a Dummy Load for some setups is a valid point. I would suggest trying it without first, and if you feel it needs it then check your equipment data for the correct Resistance/s - Impedance/s to apply.
If you have a CAT5 etc installation with symetrical INs and OUTs, then you can use a Single Relay with Quad switched contacts or 2 Relays with their Coils wired in Parallel as in my Screeny.
If you find that more gain is required to switch the Relay/s then you can easily replace the NPN Q1 with a higher gain device. This could be just a similar type with increased gain, or a Darlington Transitor eg TIP110 or equivalent which have significantly higher gain.
