Technical data
SA-IN
* For the times see the
function diagrams at the
end of the table.
The sum of currents,
which are drained from
all input modules of one
system to supply external
sensors, may not exceed
600 mA!
* Signal changes are not
detected during the test
pulse.
** Signal changes from
HIGH to LOW are not
detected during the test.
For the times see the
function diagrams at the
end of the table.
*** The response time t
AN
is the time between the
output signal arriving at the
input terminals and the
semiconductor outputs of
the associated base
module actually being shut
down. The time is
independent of the
number of input modules
connected to the base
module.
