4 Channel: This is an 4-channel signal converter. It can convert the PNP/NPN signal to NPN. Support max conversion frequency 20KHz.
Voltage Level Converter: It is also a DC 12V to 3.3V voltage level converter board. Support MCU/PLC signal level converting.
LED Indicator: Each channel is equipped with an LED indicator, making it easier to recognize their working status.
Photoelectric Isolation Module: It can be used for signal isolation, level conversion between single-chip microcomputers, PLC and other signals, PNP, NPN signal, signal level-voltage conversion, and other purposes.
Board Size:85X98X18mm/3.35 X3.86X0.71(L*W*H), Mounting Hole Pitch: 64X47mm, Hole Diameter 3mm
Specifications: Type:12V to 3.3V Channel:4 Maximum Conversion Frequency:20KHz Board Size:72X55X18mm(L*W*H) Mounting Hole Pitch:64X47mm Hole Diameter:3mm Application: signal isolation MCU/PLC signal level converting PNP/NPN signal to NPN signal signal level voltage converter Package Included: 1X 12V to 3.3V Opto Isolator Board Note: The DC power supply voltage should be the same as the signal output voltage. For example the singal is 3.3V to 5V, while the VCC=5V-------------------❤❤ Warm Prompt ❤❤-------------------This is a assemble kit that need the user to finish the assemble process.
