## Description

This DFRobot 4-channel optocoupler-isolated level converter translates 12V signals down to 5V, making it easy to interface industrial sensors and PLC outputs with Arduino and other 5V microcontrollers. Each channel features photoelectric isolation for reliable signal separation between high and low-voltage circuits. The 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. Key Features 4-Channel Optocoupler Isolation – Photoelectric isolation between input and output for noise-free signal conversion 12V to 5V Level Shifting – Converts 12V input signals to 5V output levels PNP Output – NPN-to-PNP signal conversion available Multiple Input Modes – Supports common anode, common cathode, and differential signal inputs LED Indicators – SMD LEDs show signal status on each channel DIN Rail Mounting – Enclosed in a protective shell that fits standard DIN rails Specifications Input Channels – 4 Isolation Type – Optocoupler Input Signal Level – 12V Output Signal Level – 5V Module Supply Voltage – 5V Output Current – ≤50mA per channel Bare Board Dimensions – 45 × 72 × 19mm Dimensions with Enclosure – 47 × 87 × 39mm Mounting Hole – 3mm Ideal For Interfacing 12V industrial sensors with 5V microcontrollers PLC signal level conversion NPN-to-PNP signal conversion Signal isolation between circuits Polarity and voltage level conversion Package Contents 1× 4-Channel Level Converter (12V to 5V) with enclosure Note: The module supply voltage (VCC) must match the desired output signal voltage. For this 12V-to-5V module, supply VCC with 5V. Also available in a 3.3V output version.
