Your cart is empty.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.

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.

At first, I thought I received a defective unit until I realized that I had the load wires backwards. When this happens, the circuit remains closed, which is likely the reason why other reviewers experienced the same issue. Pin 4 needs to be connected to the positive end of the power source, while Pin 3 needs to be connected to the positive end of the load. In my case, it was a 48V ebike headlight. Once I had all of the connections properly wired, the relay worked perfectly.I want to mention that the product I received looks slightly different from what is advertised; however, for my particular application, it was still compact enough to fit inside my ebike's frame.I highly recommend this product for its compact size, durability, price point, and performance.

This relay was my savior! I was trying to replace the reverse buzzer in my Club Car with a relay so that I wouldn't have to listen to that obnoxious buzzer sound. But all the mechanical relays I tried - did not work. I think the coil was drawing too much current. So I tried this relay - and whoola! It worked! I had to add a few resistors to drop the input voltage from 48V to somewhere around 16V, but other than that - I'm very happy. One item to note is that when I was testing it out, I had my ohm meter connect to the NO contacts and it appeared that it was not working. There was no continuity when I applied input voltage. I'm not sure why, but it may have to do with the output circuit needing a larger voltage to actuate the NO contacts. All I can say is - its working and I'm very happy about that!

The only important info: THESE DC-Rated SSRs WORK, and WORK WELL!Just remember to apply the + side of the "driving" power supply to terminal #4, the "positive" side of the load to terminal #3, and the "negative" side of the load to the Power Supply RETURN. For the CONTROL voltage, ensure the + side of the control voltage goes to terminal #1 and the - side of the control voltage to terminal #2. A USB cable is a PERFECT Control Voltage source (RED wire to terminal #1, BLACK wire to terminal #2).Finally, ensure the LOAD CURRENT through the relay (terminals 3 and 4) is a MINIMUM of 10 MILLIAMPS (approx.) to ensure conduction through the relay...I ** DO RECOMMEND ** these relays for switching loads up to 2 AMPS, 30 VOLTS ** MAXIMUM **.

I used this to turn on a battery connection for my ebike headlights. Battery is 58V, but signal to turn the relay on is 12v. I tried 2 of these, and both of them worked for one or two tries, but both failed after that and wouldn't turn off. They started getting hot after that as well. Max running current for the circuit is less than half an amp, but will try the higher amp version.

Hooked this thing up to a 6v input then ran a 48v through the 1 and 2 posts . The switch passed power ALL the time. No switching at all.

I’ve been using these for switching DC loads that exceed the ~20 mA capacity of the Arduino outputs and where I didn’t want to use a mechanical relay. I’ve used these with Nano and Unos. I can’t attest to the durability but no issues so far.

Used this to wire an accessory to be triggered by my car's tail lights without drawing additional power from them (even the current from a coil relay probably would've been to much). Exactly what I needed.It came in a sturdy blue package which is better than the product photo.
