Compact and efficient

Takes up very little space in the control cabinet. The heat dissipation is good even under continuous load. Great solution for mixed signal environments.

Good value

Easy to set up even for someone with limited experience. The LED indicators help troubleshoot connections quickly. Would recommend keeping the manual handy for the pinout diagram.

Reliable and fast

We installed ten of these in our packaging line. They have been running 24/7 for three months with zero failures. The response time is negligible.

Solid little device

Does exactly what it says. The build quality is decent for the price. Only minor issue is the terminal screws are a bit small, but once tightened, the connection is stable.

Perfect for PLC interfacing

I needed to connect an old NPN sensor to a new PNP-input PLC. This module worked flawlessly right out of the box. The wiring is intuitive and the signal conversion is instant.

Saved my project

I bought the wrong sensors for my automation project and didn't want to return them. This converter allowed me to use the NPN sensors with my PNP controller without any issues.

5 FAQ

Q: Can this module handle 24V DC input directly?

A: Yes, this module supports a wide voltage range from 5V to 24V DC, making it compatible with standard industrial control voltages.

Q: Can I mount this on a standard DIN rail?

A: While the module itself does not have an integrated DIN rail clip, it can be easily mounted on a DIN rail using a standard accessory mounting bracket or screw mounts.

Q: Does it work in reverse to convert PNP to NPN?

A: No, this specific model is designed strictly for NPN to PNP conversion. We offer a separate model for PNP to NPN conversion if needed.

Q: Is there a delay in signal conversion?

A: The conversion is nearly instantaneous with a response time of less than 1 millisecond, which is suitable for high-speed counting applications.

Q: What happens if I wire the polarity backwards?

A: The module includes reverse polarity protection, so accidental backward wiring will not damage the unit, though it will not function until wired correctly.
