The SEL-2407 provides time display, reliability, durability and high-accuracy timing to ± 100 nanoseconds.
SEL-2407 and SEL-2488 Product Comparison Table
The SEL-2407 is now offered with the new SEL-9524 GNSS Antenna.
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.
Simple LED status indicators
Large, easy-to-read LED display
Antenna connection (TNC)
Form C alarm contact or Form A pulse output
Wide-range power supply: 10–300 Vdc or 85–264 Vac
Optional fiber-optic port (ST), compatible with SEL-2812 Fiber-Optic Transceivers With IRIG-B
Modulated IRIG-B output
Six demodulated (three programmable) outputs (BNC)
Serial port (DB-9)
Low Price—Provides six demodulated IRIG-B time-code outputs. Three of the six outputs are user selectable for 1 PPS or 1 kPPS output. Includes built-in display without high-priced options.
Simple Operation—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.
Reliable—Apply in harsh substation environments. Exceeds IEEE C37.90 and IEC 60255 protective relay standards. Universal power supply operates from 18–300 Vdc and 85–264 Vac. Provides accurate time from –40° to +80°C.
Accurate—Apply for synchrophasor, relay event correlation, and other high-accuracy timing needs. Demodulated IRIG-B outputs with ±100 ns accuracy meet requirements for existing and future timing applications.
