Security Gateway integrates physical security capabilities.

October 8, 2014

In addition to promoting cybersecurity threat awareness, SEL-3622 offers security capabilities that enhance visibility and response time regarding physical tampering with field recloser and voltage regulator control cabinets. Detection capabilities cover sudden movement via embedded accelerometer, sudden changes in visible light via embedded light sensor, opening of doors via input sensor, and connection/disconnection of Ethernet cables. Awareness data can be sent through various mechanisms. Read More

Timers & Clocks, Services

Satellite-Synchronized Network Clock is accurate to ±40 ns.

September 15, 2014

Designed for critical infrastructure and harsh environments, Model SEL-2488 receives GNSS time signals and distributes precise time via multiple output protocols, including IRIG-B and NTP. Device provides time delay compensation for antenna cables and output cables on per-port basis to further optimize time distribution accuracy. For security, clock features Syslog Ethernet standard for event messaging, role-based accounts and LDAP for user authentication, and secure HTTPS web interface. Read More
