NPN to PNP Signal Converter / Adapter Module

The NPN to PNP Signal Converter Module converts NPN normally-open signals into PNP normally-open outputs, bridging the gap between mismatched sensors and control systems. It is an essential problem-solver for makers, students, and engineers integrating industrial sensors into automation and robotics setups. Built-in protection circuitry ensures safe, reliable operation across a wide voltage range.

Seamless sensor signal conversion

This module translates NPN.NO signals into PNP.NO signals to resolve compatibility issues between your sensors and controllers. With a fast response time of 1 microsecond, it delivers reliable real-time signal transmission.

Integrated circuit protection

Built-in surge absorption and overcurrent protection protect your controller and connected hardware from electrical anomalies. It supports a maximum load current of up to 100mA.

Clear board pinout

The module features clearly defined terminal connections for supply voltage, ground, signal input, and signal output. This simplifies assembly and reduces wiring errors during installation.

Sensor connection diagram

Connect your NPN sensor to the input side and route the converted PNP output directly to your PLC or microcontroller. The included wire connector helps you wire up the module quickly.

Operating voltage and environmental tolerance

The module operates on a DC supply ranging from 5V to 24V DC, making it versatile across logic levels and industrial power supplies. It performs reliably in temperatures from -20°C to 70°C and relative humidity between 35% and 85% RH.

Package contents

The kit includes one BM-NP NPN to PNP signal converter module and one matching wire connector.
