All points independent
(2-wire type terminal block)
Compat- Precautions for
ibility replacement
The insulation method is
different.
The rated load voltage and
current are different.
Check the specifications of
the load to be used.
Maximum switching frequency
is different.
–
Because 2 points per common
is changed to all points
independent, the wiring is
different.
