Product Description

This is a CMOS 8-bit successive approximation A/D converter that uses a differential potentiometric ladder-similar to the 256R products. This converter is designed to allow operation with the NSC800 and INS8080A derivative control bus with TRI-STATE output latches directly driving the data bus. This A/D appears like memorylocations or I/O ports to the microprocessor and no interfacing logic is needed.

Wiring schematic
I've provided a wiring schematic I found online of a similar ssr. I was having issues pinning it out, I'm not sure why maybe I'm just spoiled with diagrams. When I looked at the photo it made alot more sense and I wired it up that way, and the ssr worked flawlessly. I used this ssr to power pwm cpu fans to cool an audio amp. It gets super hot in the summer sitting in my truck and being used. I'd had a simular setup on the same amp in the past without speed control. This ssr is triggered by the remote input from the headunit, and passes voltage for my fan speed controller. This ssr is small enough I was able to fit everything inside the amp, which I did not expect, and it made the whole setup a lot cleaner in the end. It is overkill but works fine for what it is.

Nice relay for my eBike light. The power for my bike is only 6v coming from the controller and wouldn't power my light on high. After adding this relay I have no problems.
