Optocoupler Isolation Board 8 Channel

Item Type: Optocoupler Insulation Board
Material: PCB
Function: Test whether AC 220V exists.
Output TTL level: MCU can be used to test, the voltage is 3-5V.
Connection: Output can be connected to PLC 24Vb.
When the voltage of 220V is normal, the isolated photoelectric module emits a low level. When the 220V is off, it emits a high level, the output can be connected to PLC 24vb
When connecting the PLC input, the COM terminal is connected to the 24V power supply, the input terminal is connected to the S1-S8 signal output of the board, and the GND optocoupler is connected to the negative pole of the power supply.
Channel optocoupler board adopts high quality PCB material, not easy to malfunction, very durable for long-term use, small size, lightweight
The blue terminal 5.0 of the optocoupler photoelectric isolator module is connected to the voltage of 220V, and the yellow pin is the signal output, convenient for you to use and install

Optocoupler Isolation Board 8 Channel PLC 24Vb Voltage Detection Module Level Conversion Board 220V AC for MCU Testing
APPLICATION: The voltage detection board is used to detect whether there is 220V AC, you can also use MCU to perform tests, and the working voltage is 3-5V
