LOGO I-SENSOR Diagrams

Greetings & Good Afternoon,

I've purchased some I-Sensor circuits from Uxcell Products. They are a simple Toroidal current transformer with a rectifier and relay on board. The actual product I purchased has an ID on back:
Logo-I-Sensor v1.1. It scales 0-5A and runs from 5v.

Does anyone know how to obtain a circuit diagram/schematic or pin out for these things?
There's three pots on board, obviously one can play with this thing and figure out stuff, but I'd
prefer to RTFM...

Thanks,
STeve

Hello, I have the same problem and I have found this same thing serves you something.

Hi,

I recently bought a Logo-I-Sensor v1.1. through AliExpress. It contained a currenttransformer 1000:1 for 50A to 50 mA.

I managed after some laboriously staring and checking about all connections with a Multimeter (in connection mode) to reverse-engineering the circuitry.
Mind, I could not find the exact capacitance for the small smd capacitors, nor the type of transistor used and the diodes.
So you'll have to check it.

I hope this will help someone
