The SEL-2407 provides time display, reliability, durability and high-accuracy timing to ± 100 nanoseconds.
Accurate Time Synchronization—Synchronize relays, phasor measurement units, Sequential Events Recorders, information processors, and other devices by using a GPS time source and IRIG-B outputs. The SEL-2407 Satellite-Synchronized Clock provides ±100 ns average timing accuracy (±500 ns peak) for IEEE C37.118 control function extensions for synchrophasors as well as event correlation and reporting.
Reliable Operation—Install in harsh substation environments. IEEE C37.90 and IEC 60255 design standards ensure accurate timing over a temperature range of –40° to +80°C (–40° to +176°F) and in the presence of electrical surges and power supply variations.
High-Power Outputs—Use one modulated and six demodulated IRIG-B outputs to synchronize relays directly or through an SEL information processor.
Substation Time Display—View the built-in LED time display for convenience in the substation.
Simple Operation—Program time offsets and output formats with easy-to-operate control (DIP) switches mounted behind the front panel. Settings can be made without removing the SEL-2407 from its mounting location.
Fiber-Optic Port—Time-synchronize devices over fiber-optic links by using the optional 850 nm fiber port. Fiber-optic connections improve safety, signal integrity, and reliability in harsh electrical environments.
