Perfect for PLC Integration

I needed to interface an old NPN sensor with a new PNP-input PLC. This module worked flawlessly right out of the box. The wiring is straightforward thanks to the clear labels on the terminal block.

Works well, terminals are small

The conversion logic is perfect and noise-free. However, the screw terminals are quite small, making it difficult to connect thicker gauge wires. Stick to 22-24 AWG for best results.

Reliable but runs slightly warm

Does exactly what it says. I have three of these running in a control cabinet for 24/7 operation. They get a little warm to the touch under full load, but performance has been stable for months.

Compact and Efficient

Small footprint fits easily into tight junction boxes. No configuration needed, just wire power and signal. It handles the voltage drop very well across the 5V to 24V range.

Saved us from replacing sensors

We had a batch of NPN sensors that didn't match our new machinery inputs. Instead of buying new sensors, we bought these converters. Cost-effective and robust solution.

5 FAQ

Q: Does it work with magnetic reed switches?

A: Absolutely. As long as the sensor outputs an NPN signal, this module can convert it to PNP regardless of whether it is photoelectric, proximity, or magnetic.

Q: Can this module handle a 24V DC input signal?

A: Yes, this converter supports an operating voltage range of DC 5V to 24V, so it works perfectly with 24V systems.

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

A: Yes, the module is designed with mounting holes compatible with standard DIN rails or can be screwed directly onto a panel.

Q: Is there any delay in signal conversion?

A: The response time is less than 1 millisecond, which is negligible for most industrial and hobbyist applications.

Q: What happens if I reverse the polarity?

A: We recommend double-checking wiring before powering on. While the module is robust, reversing power polarity may damage the internal components as there is no explicit reverse polarity protection listed.
