C1 DIN3 Digital input 3
{ON right}
Digital input as per
EN 61131-2, Type 1
Low: 0-5V (~ 9.5k
Ω)
High: 15-30V
(~ 2.5-3.5k
Ω)
Input capacitance: 10nF
Scanning time: 1ms
Reaction time:
≥ 4ms
Digital input for the evaluation of a
connected initiator. This input is
transferred to the control unit
directly via the AS interface or the
PROFIBUS. It is not evaluated by
the starter.

26.5 – 31.6V,
max. 240mA
For control of the SK 1x5E via the
simple field bus level.
By means of jumpers it can be
selected whether only the "yellow
cable" is used, or "yellow" and
"black", i.e. supply with additional
auxiliary power.
