5.2 Wiring transducers to analogue inputs
The device has two analogue inputs, which can work in one of the selected modes:
0/4-20mA (active/passive transducers), R/RTD type input, U type input. It should be taken
into account that the configuration of jumpers inside the device is necessary. Detailed
description is in section
Configuration of jumpers inside the device
