Digital inputs
The UMG 510 has 8 digital inputs arranged in two
groups of 4 inputs each.
Each group of inputs has its own common ground
terminal and is insulated to the internal circuits as
well as to the other group of inputs. Active inputs re-
quire an input voltage of 10..28V at max. current of
6mA.

digital outputs.

Digital outputs
The UMG 510 has 5 digital outputs. The outputs are
insulated from the internal electronics. The output
transistors are arranged as high side switches with
common plus terminal (terminal no. 11). Each tran-
sistor can drive 30mA and withstands max. 28V
open circuit voltage.
