{"title":"4-Channel Level Converter (12V to 3.3V)","handle":"4-channel-level-converter-12v-to-3-3v","url":"/products/4-channel-level-converter-12v-to-3-3v","description":"This DFRobot 4-channel optocoupler-isolated level converter translates 12V signals down to 3.3V, making it easy to interface industrial sensors and PLC outputs with Arduino, Raspberry Pi, and other 3.3V microcontrollers. Each channel features photoelectric isolation for reliable signal separation between high and low-voltage circuits.\n\nThe module supports common anode, common cathode, and differential signal inputs with PNP output (NPN-to-PNP conversion available). It mounts on standard DIN rails via the included enclosure, making it suitable for panel installations in industrial and automation environments.\n\nKey Features\n\n\n4-Channel Optocoupler Isolation – Photoelectric isolation between input and output for noise-free signal conversion\n\n12V to 3.3V Level Shifting – Converts 12V input signals to 3.3V output levels\n\nPNP Output – NPN-to-PNP signal conversion available\n\nMultiple Input Modes – Supports common anode, common cathode, and differential signal inputs\n\nLED Indicators – SMD LEDs show signal status on each channel\n\nDIN Rail Mounting – Enclosed in a protective shell that fits standard DIN rails\n\n\nSpecifications\n\n\nInput Channels – 4\n\nIsolation Type – Optocoupler\n\nInput Signal Level – 12V\n\nOutput Signal Level – 3.3V\n\nModule Supply Voltage – 3.3V\n\nOutput Current – ≤50mA per channel\n\nBare Board Dimensions – 45 × 72 × 19mm\n\nDimensions with Enclosure – 47 × 87 × 39mm\n\nMounting Hole – 3mm\n\n\nIdeal For\n\nInterfacing 12V industrial sensors with 3.3V microcontrollers\nPLC signal level conversion\nNPN-to-PNP signal conversion\nSignal isolation between circuits\nPolarity and voltage level conversion\n\n\nPackage Contents\n\n1× 4-Channel Level Converter (12V to 3.3V) with enclosure\n\n\n\nNote: The module supply voltage (VCC) must match the desired output signal voltage. For this 12V-to-3.3V module, supply VCC with 3.3V.\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2693,"title":"Default Title","sku":"DF-DFR0913","price":14.38,"on_sale":false,"in_stock":true,"available_quantity":17,"option1":"Default Title"}]}
