It may not need mentioning, but when you drive solenoids a back swing diode should be put across the coil or you may damage solid state outputs. Some solenoid drivers already have this.
I have found that in addition to a diode a small ceramic cap (100 nF or 0.1 uF) in series with a 2 to 5 ohm...
I just learned that this IS an elegant circuit. I was told in college oh so long ago that mosfets were polarized devices like transistors (I think by a Professor appropriately named Looney).
This is functionally true. However if the gate is positive with respect to the source current can flow in...
Maybe I'm missing the point and I'm not familiar with these processors but you could simply toggle a bit in one processor, have a remote processor copy the bit to a second bit and time how long it takes the first processor to see the changed 2nd bit. If you toggled it 100 times (or more) and...
This is too vague to be answered. Are you talking about a PLC connected to the internet for monitoring; protecting the program from being copied; or what?
I personally like PLC direct. They have a broad line of PLCs and you can actually talk to a knowledgeable person in technical support (on...
To VE1BLL: I would use option 1 but the customer used option 2 and messed it up with both sides of the mosfet connected to logic ground, effectively eliminating the mosfet. I don't understand the circuit, the person who designed it isn't available and they need a completed (and presumably...

I am revising a circuit board and have a problem with part of the design. There are clear errors (beyond my question here) but I don't understand the circuit so I'm not sure how to fix it. The data sheet for the VNH3SP30-E, figure 33 (... short circuit protection) shows a N MOSFET with the...
