Fail safe stand-alone remote isolation system with continuous self-diagnostics
Time to isolate and lock out is as short as three minutes
Automated process completes isolations remotely without requiring the presence of personnel in substations or switchrooms, avoiding the risk of arc flash
Multiple independent verified points of isolation
Networks to existing plant DCS or SCADA system
Maintains integrity on power or communications outage
After installation, a time functionality proof test (TFPT) is required
Can perform up to the requirements for SIL3 and CAT4
