Greetings,
The synopsis: I'm trying to figure out how to home a linear actuator to a point approximately halfway between its two extremes.
Pertinent details:
The device is driven by a precision linear actuator with a movement per step of 1.5 microns (the linear acutator is driven by a stepper...
I've got a TTL level digital input card that's started popping channels. I suspect a wiring fault in our cabling or test unit is temporarily tossing 24VAC onto the input line which the input card can't hold off.
So, I'm looking for a protection solution somewhere this side of full-blown...
I've been working on reverse engineering a resistive load bank control board that controls a 750 Amp load bank. My problem is that I don't see how the trim transistors keep popping.
Here are some of the fun details:
The board controls and trims a set of amplifiers that work to turn on the main...
