Moore Industries SSX and SST safety isolators and splitters

Thursday, 08 August, 2013 | Supplied by: Moore Industries Pacific Inc



Moore Industries’ SSX and SST safety isolators and splitters provide reliable isolation and signal conversion for HART data in functionally safe process control settings. The 2-wire (loop-powered) SSX and 4-wire (line/mains-powered) SST have been certified by exida for single use in safety instrumented systems up to SIL 2. Comprehensive FMEDA-certified safety data is available on request.

The SSX and SST family protects 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. It also has 1500 VRMS of isolating capability to protect safety I/O cards and systems from surges, spikes and transients in the field. Standard 20 V/m RFI and EMI protection stops damages caused by radio frequencies and electromagnetic interference.

Sending HART data is critical for diagnostic and preventative maintenance. While most isolators ‘strip off’ HART data, the SSX and SST pass along HART data to asset management systems, programming devices or host systems. In addition, the SSX stops ground loop noise and solves bucking power supply problems caused when two devices try to source power to the same loop.

The 4-wire SST splitter takes the input from one process signal and creates two identical, isolated outputs that can go to two different monitoring or control devices. It can also serve as a HART splitter to pass HART data to one or both independent outputs.
