1 Channel AC 220V Optocoupler Isolation Module

This is a 1 Channel AC 220V Optocoupler Isolation Module with High Voltage Opto Isolator, with 3-5V Power Supply. It can be used to detect the existence of 220V AC Output at TTL level which can be detected with the help of a microcontroller. The power supply can be 3 to 5V. This module can also access PLC24V level.

The 1 Channel AC 220V Optocoupler Isolation Module contains an input circuit and an output circuit, which are electrically isolated from each other. The input circuit is connected to the low-voltage side of the system, while the output circuit is connected to the high-voltage side. The isolation between the input and output circuits is achieved using an optocoupler, which is a device that uses light to transmit electrical signals.
