Analog switches are like electronic (vs electro-mechanical) relays.Not being mechanical, they are much faster than relays, and the control input is much lower power than a relay coil. But like op a...

You've got a fundamental issue with T1 in that if V2 is 2 volts, you won't have enough Vgs swing to turn T1 on. I'd look at using something like the ADG1419 analog switch rather than the FET. You'...

The 741 op amp is totally inadequate for a 25 MHz signal. (741 gain bandwidth is around 1MHz). The comparator is also likely to be totally inadequate, depending on whether V2 falls within the range...

Before even getting to the op-amp portion of the circuit, I think I see another problem. It looks to me like you have the pinout wrong on IC2, the LM311D. From the data sheet for the LM311D:From yo...

I don't have the pro version, but with the standard version, the plot settings are stored in files with a .mop extension. The first part of the .mop filename is the same as the .pcb file (or possib...

Frans, do post if you find a solution.As near as I can tell from some quick searching, plotters are treated as printers under Windows. After Windows 8, Microsoft stopped including their sample plot...

It looks like the main element you are missing is a logic inversion circuit between the output of the touch switch and R2 in your schematic. The touch switch, per their diagram, expects one side of...

To implement a solution correctly, you also need to know more details about what conditions should signal alarm, and how quickly it needs to be signaled. You've said what the output of the generato...

"May I can find a relay that will energize at say 6VDC and yet handle the generator's 120VDC."That brings up another question: What is the minimum output of the generator when it is working?Most re...

What sort of load is the alarm, in terms of DC or AC, max voltage, minimum and maximum current?This determines the necessary contact rating on the relay. (Or substitute for the relay.)And why a 6V ...
