FSSeries Product Chart



Functional Safety Products Designed and Built for your Process

The Moore Industries FS Functional Safety Series instrumentation gives you layers of protection that reduce risk and deliver reliable performance when you need it most.

  • Designed and built from the ground up for use with confidence in your Safety Instrumented System (SIS).
  • Full third-party certification to IEC 61508 eases burden of proven in use on unapproved products.
  • SIL 2 and SIL 3 capable product family designed to meet your safety loop instrumentation needs.
  • Operating temperature range of -40 to 85°C for the most demanding environments.


All FS Series Instruments Feature:

  • Standard 20v/m RFI/EMI Protection: Special circuit and enclosure designs protect against the harmful effects of radio frequency interference (RFI) and electromagnetic interference (EMI).
  • Rugged Housing: All instruments are available in either a rugged and durable aluminum DIN-rail case or housed in a field mount explosion-proof or flameproof enclosure.
  • Certificates: exida® certificates for Functional Safety Series products are available for download on our website ( or exida’s website (
  • FMEDA reports are reviewed and endorsed by exida. Because each report is specific to hardware and firmware versions, all FMEDA reports are sent upon request so we can guarantee that you always have the latest version.

SLA-2023-08-LookRightSLA Multiloop & Multifunction Safety Logic Solver and Alarm

The SIL 2/3 capable SLA Multifunctional Safety Logic Solver and Alarm performs as a single or multi-loop logic solver that incorporates enhanced math, voting and logic capability to act on potentially hazardous process conditions in Safety Instrumented Systems (SIS).
