The 2-Channel Level Converter translates 12V signals down to 5V using optocoupler isolation, making it easy to interface industrial sensors and PLC signals with 5V microcontrollers like Arduino. It supports common anode, common cathode, and differential signal inputs with PNP output (NPN to PNP conversion available).
The module includes SMD LED indicators for each channel and comes in a DIN rail-compatible enclosure for clean installation in industrial and prototyping environments.

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- differential signal
- A measurement taken between two input wires rather than between one wire and ground. This matters for precision sensors because it can reduce noise and lets the ADC read very small voltage differences more accurately.
- DIN
- As a pin label, DIN stands for 'data in', the input through which a device receives serial data from a controller, as found on SPI displays, LED drivers and other serial modules. DIN can also refer to the German standards body of that name, as in a round multi-pin DIN connector or DIN-rail mounting.
- DIN rail
- DIN rail is a standard metal mounting rail used inside industrial electrical cabinets. When a product is DIN rail mountable, it can be clipped neatly alongside power supplies, relays and other automation hardware in a panel.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- SMD
- SMD means surface-mount device, a component style designed to be soldered directly onto the surface of a circuit board rather than through holes. SMD parts are compact and mounted flat on the board, which suits smaller and mass-produced designs.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
