MA 2107-A005 EN 30
8 Inputs
The control inputs pulse Control , Motor direction, Boost , Activation and Reset are
electrically insulated by optocoupler from the MSX supply voltage (+U
B
). This assures best
noise suppression between control and power circuit. The signals are active, when current
flows through the optocoupler.
8.1 MSX 5 V Standard and MSX 5 V RESET Inputs
All inputs include an optocoupler with series resistors 2 x 180 Ω. The optocoupler inputs
are internally connected via 180 Ω to +5 V.
The MSX inputs are controlled via open-collector. The supply voltage of the optocouplers,
5 or 24 V, is connected to pin 10ac (admissible range: 4...32 V
DC
).

8.2 MSX 24 V Input
All inputs include an optocoupler with series resistors 2 x 2.2 k Ω.
The MSX inputs are controlled via open-collector. The supply voltage of the optocouplers,
of 24 V, is connected to pin 10ac.
