SpARE pARTS
Refer to “Replacement Parts” in the UD10 instruction
manual. Safety Certification is based on a sufficient
number of spares to achieve a 24 hour mean time to
repair.
CERTIFICATION AND FAILURE RATE DATA
All Safety-Certified UD10 models are certified compliant
to:
IEC61508: 2010
Type B Device
Systematic Capability: SIL 2 certified
HFT: 0
Low Demand Mode
PFDavg should be calculated for any safety instrumented
function using the UD10. (Refer to FMEDA report for
necessary information, including DU rate.)
Safety Accuracy:
<4% error (see
SPECIFICATIONS section
of instruction manual for
performance details).
Safety Response Time: The UD10 contributes less
than 2 seconds to the worst
case safety response time.
Product Life: 10 years, based on
manufacturer data.
All failure rate data for SIL verification is in the FMEDA
report, which is available upon request.
ADDITIONAL CERTIFICATIONS
FM, CSA, ATEX, IECEx, CE, INMETRO (Brazil),
VNIIFTRI (Russia).
Refer to the Model UD10 Instruction Manual for details.
