Max. 120 mA at a test output (X1 or X2)
Thus, a maximum of eight testable sensor cascades
are possible per module with a maximum of 30 mA
each.
The total current of the samosPRO system is limited
to a maximum of 1.28 A. This corresponds, for exa-
mple, to a maximum of 32 testable sensor cascades
with 30 mA each plus 64 tactile sensors at the in-
puts of expansion modules with 5 mA each.
