1/3/8 Channel AC Optocoupler Isolation Module 220V Voltage Detect Board for PLC Access

Feature: 1. Output TTL level, can be detected with the microcontroller. The power supply can be 3‑5V. 2. 1 channel 220V AC optocoupler detection module. It can be used to detect the being of 220V AC. Can also access PLC24V level. 3. Then the PLC input terminal of the PLC COM power supply 24V input termination of the board output OUT, optocoupler board GND power negative. 4. Green 2P 5.0 terminal connected to 220V voltage. 3P terminal connected to the microcontroller input. 5. Great workmanship, can perfect replacement for the old . Small size, easy to carry and store, convenient to use and with good performance. Specification: Item Type: Optocoupler Module Material: PCB Color: As shown in the picture Application: Test 220V AC Package List: 1 x Optocoupler Module Note: When the power module in the power of the board after the white wire frame can not touch any device. because it is high voltage. Note the safety of electricity.
