Notes
The SpeedSys300 ODS301 module
is a single channel device. It has
three separate input interfaces for
connection to different types of
speed sensor / measurement chain
but only one measurement channel
can be configured and used by the
module at any one time.
*
Only Safety relay 1, Safety relay 2
and the Analog output are safety
outputs. No other outputs should be
used to implement a safety function.
