Reliable—Exceeds IEEE and IEC Relay Standards

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. Accurate operation from —40° to +80°C.

Accurate

Apply for synchrophasor, relay event correlation, and other high- accuracy timing needs. Demodulated IRIG-B outputs with ±100 nsaccuracy meet requirements for existing and future timing applications.

Low Price—High Function

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

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.
