SSX/SST: Safety Series Isolator and Splitter

SSX/SST: Safety Series Isolator and Splitter
Part of Moore Industries’ FS Functional Safety Series, the exida® approved, SIL 3 capable 2-wire (loop powered) SSX and 4-wire (line/mains powered) SST Safety Isolators and Splitters provide isolation and signal conversion for your SIS (Safety Instrumented System) needs. These units protect and enhance loops and also pass valuable HART® data from the field transmitter to host systems and vice-versa.

Isolate your SIS from your Basic Process Control System or monitoring system so disconnections or failures to these secondary systems don’t affect your safety system. FMEDA (Failure Mode Effects and Diagnostic Analysis) reports are available with the required safety data to ensure that risk reduction requirements are met.

With built-in HART pass-through technology you can rest assured that when your loops use HART transmitters that critical and valuable HART diagnostic, process, and calibration information can be read on either side of the SSX/SST. Most all other isolators block and “strip off” the HART signal.
