Discussion Overview

The discussion revolves around the conversion of an NPN signal from a sensor to a PNP signal suitable for a gauge. Participants are seeking circuit diagrams or simple solutions for this conversion.

Discussion Character

  • Technical explanation, Debate/contested

Main Points Raised

  • One participant describes the problem of needing to convert an NPN output from a sensor to a PNP input for a gauge, mentioning the specific wiring configuration of both devices.
  • Another participant requests a diagram of the circuits involved to better understand the issue.
  • A further reply emphasizes the necessity of seeing the circuit to provide meaningful assistance.

Areas of Agreement / Disagreement

Participants generally agree that a circuit diagram is essential for addressing the conversion issue, but no consensus on a solution has been reached.

Contextual Notes

The discussion lacks specific details about the wiring and operational characteristics of the NPN sensor and PNP gauge, which may be critical for developing a conversion method.

Hello All,

I have a sensor which outputs an NPN signal, however, the gauge it connects to only inputs PNP signals, how can i convert the NPN to PNP?

I have tried looking for circuit diagrams and simple converters but I have found nothing, all help appreciate.

Thanks

Very nebulously phrased question. Got a diagram of the two circuits?
 
Basically, the NPN sensor has three wires coming out of it and the gauge had an input of three wires, however, the gauge requires PNP not NPN, so i need to convet the NPN to output PNP
 
It's a case of really truly needing to see the circuit!
