Safety Manual
9106 HART® transparent repeater
Note
1
: The 9106 contains no lifetime limiting components, therefore the PFH
figures are valid for up to 12 years, according to IEC 61508.
Note
2
: The use of 9106 in SIL 3 applications requires that the connected PLC is
suitable for SIL 3 applications. see paragraph 4.6.
Note
3
: Depends on detection time in external controller. If detection time is xx
seconds, the Demand Rate shall be 100 times xx seconds.
Note
4
: Simple device (type A) where microprocessors and software have no
effect on safety output.
8. Hardware and software configuration.
All configurations of software and hardware versions are fixed from factory, and
cannot be changed by end-user or reseller.
This manual only covers products labelled with the product version (or range of
