## Questions & Answers

**Q: i noticed this has ac and dc power inputs. can i operate 2 ac lights and 2 dc fans simultaneously**
A: Important to note that the outputs have NOTHING to do with the power supplied to the unit on the 4CH Pro and 4CH Pro R2. Supplied power is for the electronics only. You will need additional power source(s) - in addition to the power for the electronics -for the devices you are controlling via the relays/switches.

**Q: What are the differences between 4ch, 4ch pro, 4ch r2 and 4ch r2 pro?**
A: Just by looking at the pics and specs displayed it appears that the two 4CH units (WITHOUT PRO) use the same power source (90-220 AC) for the electronics AND the connected devices). Both the models with PRO use the supplied power ONLY for the electronics and you would supply power separately to the external devices controlled by the switches.

**Q: What is the amperage limit / ampacity of this unit?**
A: This is 10 amp /loaf with a wifi. & 433 MHz

**Q: How do you change modes between interlocking, self locking and inching?**
A: Hello that is done with the DIP switches. I don't have the manual in front of me but if you go to the webpage for the device you can get a PDF version. 

If I remember correctly it was better than the one on the box and clearly showed how to set them.

Me lo recomendó la IA para controlar mi aire lavado por wifi o Alexa y cumplió perfectamente. Lo que sí podría mejorar es el tamaño de los bornes para meter los cables
