EHELP: SPA2 has SIL2 rating

EHELP: SPA2 has SIL2 rating

Q: Does your SPA2 have a SIL 2 rating?

A: The SPA2 can be used in safety instrumented systems (SIS) as long as the appropriate safety-related data and restrictions in use are reviewed and followed by a competent safety practitioner. We have a FMEDA (Failure Modes, Effects and Diagnostics Analysis) report that provides this data for the SPA2, and is available upon request.

We also offer the STA Functional Safety Limit Alarm Trip, which is expressly designed for safety related applications and has third party certification (exida) per IEC 61508:2010 for systematic integrity up to SIL 3 and for random integrity up to SIL 2.

The exida certified FMEDA data can be provided and used by a competent functional safety practitioner to calculate the required PFDavg and determine the SPA2s or STAs SIL capability and overall suitability in your Safety Instrumented Systems (SIS). For more information, check out the download page for the SPA2.
