Need help to identify a PCB
This seems to have a AC-DC power supply (transformer, diode bridge...), relays and inputs/outputs.

It seems to be designed to control stuff using relays (motor, two SOLenoids, a buzzer...) so it probably comes from some sort of machine which uses these actuators.

If the chip with the Korean label on top is a standard chip and not a programmed microcontroller, then sending standard digital levels into the input pins may allow you to control the relays and use this in one of your projects if you need a relay board.
