Photo sensor output too weak to drive relay or step-up module

Customer:

The LED indicator doesn’t matter. The sensor works at 24V but I still get 4.7V digital output when I need 24V for the PLC to recognize it. The problem is that the current from the sensor output cannot drive a step-up controller. Do you have any ideas how I could solve this most simply?

Nije mi bitna ledica. I to radi na 24V ali i dalje imam 4,7V digitalni izlaz a treba mi 24V kako bi ga PLC prepoznao. Sada tu mi se javlja problem šta struja koja izlazi iz senzora nemože upogoniti neki step-up kontroler. Dali imate možda neku ideju kako mogu najjednostavnije riješiti ovaj problem?

What do you mean by “step-up controller”?

na što mislite pod “step-up kontroler”?

Customer:

I’m referring to this step-up regulator: https://www.chipoteka.hr/artikl/132070/

But if we ignore that, there’s also a simpler solution. For example, if I put a relay on the output of your photo sensor, will it have enough power to activate it? I’m looking at this relay available in the Chipoteka warehouse: https://www.chipoteka.hr/artikl/18060/

Or do you perhaps have a relay in your product line that I could use for this purpose? What’s most important to me is to somehow manage to activate an input on a Mitsubishi PLC FX series that responds to 24 VDC.

Radi se o ovom step-up regulatoru: https://www.chipoteka.hr/artikl/132070/ ali ako zanemarimo to postoji i jednostavnije riješenje. Recimo da na izlaz Vašeg foto senzora stavim relej. Dali će on imati dovoljno snage da ga aktivira? Radi se o ovom releju koji imaju u chipoteci na lageru: https://www.chipoteka.hr/artikl/18060/ Meni je najbitnije da na neki način uspijem aktivirati ulaz na Mitsubishijevom PLC-u FX serije koji reagira na 24 VDC.

Soldered Support:

I can check with a colleague about when we could prepare a finished module for you. For the quantity you mentioned, it would certainly be a more cost-effective and practical solution.

If you need this urgently, I can suggest a step-up and relay from our product range:

treba li Vam hitno ovo rješenje? Provjeriti ću s kolegom kada možemo izraditi gotov modul za vas. Za količinu koju ste spomenuli svakako bi bilo jeftinije i praktičnije rješenje.

Customer:

The package arrived but unfortunately the sensor doesn’t have enough power to activate the relay. Do you have any ideas how I could try to solve this?

Original message (Croatian)

Stigao mi je paket i nažalost senzor nema snage da aktivira relej. Dali imate kakvu ideju da to probam riješiti?..
