Optocoupler Isolation Board 8 Channel PLC Voltage Detection Module 220V AC for DIY
Optocoupler Isolation Board 8 Channel PLC Voltage Detection Module 220V AC for DIY
Specification: Item Type: Optocoupler Isolation Board Material: PCB Function: Test whether AC 220V is applied. Output TTL level: MCU can be used for testing, voltage is 3-5V. Connection: Output can be connected to PLC 24Vb. Package List: 1 x Optocoupler Isolation Board Note: After turning on the module, do not touch any part of the white wire frame on the board because it is high voltage. Pay attention to electrical safety.
Product Features
- PLC connection: When connecting the PLC input, the COM terminal is connected to the 24- V power supply, the input terminal connected to the signal output S1-S8 of the board, and the optocoupler GND connected to the negative terminal of the power supply.
- Level output: When the 220V voltage is normal, a low level is output. When the 220V is turned off, it outputs a high level.
- Working Tips: The blue 5.0 port is connected to the 220V voltage, and the yellow pin is the signal output.
- Voltage detection: Used to detect whether there is 220V AC, also can use MCU for testing, and the working voltage is 3-5V.
- Good material: Using high quality PCB Material, not easy to fail, very durable for long term use.
