Whatever is on the other side is irrelevant, and if it's designed with some unknown source resistance to drop the voltage down, it's no longer 24 volt. The question isn't about designing drivers for this unit - he already has those. | |

| Oct 7, 2016 at 1:12 | comment | added | user207421 | @pe There are inputs with what source impedance? Is it really just a battery? | |
| Oct 6, 2016 at 20:53 | comment | added | pipe | There is no "previous driving stage". These are inputs that takes a voltage from 2.2 up to 24V. | |
