4.3.1 Analog outputs

The two analog outputs of the converter are default active, sourcing 4...20 mA into a load of
maximum 450 Ω. They are galvanic isolated from the rest of the system, but the two channels
use a common ground.

Channel 2 can be jumpered to be passive, and fully isolated sink 4...20 mA from an external
supply of max. 24 VDC, by changing JP1 and JP7.
