Compat- Precautions for
ibility replacement
Wiring must be changed.
Existing wires can be used but
applicable crimping terminals
are different.
For details, refer to Section
6.3.
Operating voltage range is
different.
Because the current
consumption has increased,
the current capacity must be
reviewed.
The shape is different.
Because mounting hole size is
× different, reworking is
required.
The A20XB-16UD can be
mounted to the existing DIN
rail.
