SMCI33
Connections and circuits
Function of the inputs
All digital inputs – with the exception of the "Clock" input in the clock directional mode
– can be freely programmed using the NanoPro software (e.g. as a limit position
switch, enable, etc.) and can be used for sequential control with NanoJ.
All inputs can be configured for “active-high" (PNP) or “active-low" (NPN) with
NanoPro.
Input circuits
All inputs (apart from the "Analogue In" input) are electrically isolated by optocouplers
from the voltage supply of the SMCI33 and designed for 5 - 24 V input signals at an
input current of 10 mA.
Note:
The voltage must not exceed 24 V. It should drop below 2 V for safe switching off and
be at least 4.5 V for safe switching on.
Output circuits
The outputs are transistor outputs in Open-Collector circuits (0 switching, max. 30 V /
30 mA). An LED can be integrated to test the output. The LED lights up when the
output is active.
