1 Channel 220V AC Optocoupler Isolation Module for PLC

1 Channel 220V AC Optocoupler Isolation Module for PLC is a High Voltage Opto Isolator 3-5V Power Supply PLC Photoelectricity Coupler Module. 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. This one channel 220v Optocoupler 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. Features: Output TTL level can be detected with the microcontroller. The power supply can be 3-5V Can also access PLC24V level Then the PLC input terminal of the PLC COM power supply 24V input termination of the board signal output OUT, optocoupler board GND power negative Blue 2P 5.0 terminal connected to 220V voltage 3P terminal connected to the microcontroller input. Specifications :  Board Size: 73 x 15mm Function: Testing whether AC 220V exists Output TTL Level: can use SCM to test, voltage is 3-5V Adaptive to PLC 24V level Safety Warning: 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. Package Includes: 1 x 220V AC Optocoupler Isolation Module for PLC
