Oh wow. That's almost exactly what I'm looking for, except I need about 20 amps. Did you just go through each product and look at the schematics? I'm unable to specify a proper search that returns what I am looking for. I try to consider a class of SSR's and see if they have the back-to-back...
You are right on all counts. It's the coil current tyat has me worked up. I keep revisiting this in my mind, and perhaps I should just stick with relays.

Ah. I just pulled up the schematic for that. Yes, it's optically isolated. I was using isolation in a different...
I've looked at some DC SSR's, namely the Crydom ones where I could find a schematic. These do not offer isolation, they allow reverse current when not enabled. I initially tried an AC relay, but due to its zero crossing sensing, it was unreliable when switching a load. I would love to buy off...
Hobbyist here, and my first post.
I need to implement an ideal switch in a MOSFET. This is in a vehicle with multiple batteries, and I would like to manage these with the following functions:
1) Isolate a battery
2) Join the batteries
I made a PC board with ST Micro VN31, which is an IC SSR...
Would the schematic in this evaluation board work for the Sponsler pickup coil?

Actually, I just want the vane crossing events to be CMOS compatible. I have source code for a magnetic flow meter.
The signal drives an interrupt which counts the pulses, accumulates and calculates rate and sends it via SMBUS.
Almost all of my experience is with digital circuits, and I've...
I did look it up. Sorry, I don't have the flowmeter with me, but specs on this sort of equipment are very difficult to find. Just discovering the fact that it's RF pickup was about all I could find.
I believe their interface circuit costs about $350, and I'm very certain it's just as simple...
I bought a used flowmeter that has an RF coil rather than inductive pickup in order to measure very low flow rates. This type of pickup does not introduce cogging that happens with the magnetic pickup.
I have never interfaced to this type of sensor. It looks very similar to LVDT type of...
