Switching Repeater Type 9170
The electronic output is optimized for
the application along with active I/O
cards. In case of passive I/O cards
the potential for the generation of
High Level is missing.
The High Level can be generated if an resistor
is connected externally to the supply voltage
(e.g. +5V).
