SSX/SST: Safety Series Isolator and Splitter Receives Renewal for exida® Certification

SST Family Moore Industries ppMoore Industries SSX and SST Safety Isolators and Splitters receive renewal for exida® certification. With full third-party exida certification to IEC 61508 standards, you don't have to carry the burden of continuously documenting and archiving proven-in-use data on unapproved products The SSX and SST are part of the Moore Industries FS FUNCTIONAL SAFETY SERIES and provide reliable isolation and signal conversion in potentially hazardous environments.

The two-wire (loop-powered) SSX and four-wire (line/mains powered) SST have been re-certified by exida for single use in Safety Instrumented Systems up to SIL 2. The SSX and SST also have cFMus certifications for use in both General (safe) and Hazardous Locations. This means that the SSX and SST can be used in process areas and industries where potentially explosive gases and vapors may be present including:

  • Oil and natural gas refiniries
  • Offshore oil and gas rigs
  • Chemical, petrochemical, and pharmaceutical plants

The SSX and SST are ideal products for use in settings where safety is critical. They protect safety systems by isolating an SIS from basic process control or monitoring systems so that disconnections or other failures don’t impact the safety system. Both models offer 1500Vrms of isolating capability to protect safety I/O cards and systems from surges, spikes, and transients in the field. Standard 20V/m RFI and EMI protection stops the harmful effects caused by radio frequencies and electromagnetic interference.

While most isolators strip or block HART signals, the SSX and SST were designed with pass-through capability. With this built-in HART pass-through technology you can rest assured that when your loops use HART transmitters critical and valuable HART diagnostic, process, and calibration information can be read on either side of the SSX/SST.

FMEDA (Failure Mode Effects and Diagnostic Analysis) reports for the SSX/SST are available with the required safety data to ensure that risk reduction requirements are met. Do you want more information? Do you want more information? Download the data sheet. Or visit the catalog.
