IoT-Vertebrae
Contingut
Atenció!
- Els potenciòmetres de 10K han de dur un resistor de 14K en sèrie a l'alimentació. Així, quan s'alimenten a 24 volts poden donar una tensió entre 0 i 10 volts (per a connectar a la placa d'entrades analògiques. Tot i que les entrades poden ser de -10 a + 10 volts).
- A la serigrafia NPN/PNP de la placa de sortides digitals està invertida. Per tant, el pont (jumper) és a NPN fa que les sortides siguin PNP. I si el pont (jumper) és a PNP fa que les sortides siguin NPN.
