SEL-2404

Satellite-Synchronized Clock

SEL recommends selecting the SEL-3401 paired with the SEL-2401, SEL-2407, or SEL-2488 in place of the SEL-2404.

Replacement products: SEL-3401 Digital Clock with either SEL-2401 Satellite-Synchronized Clock, SEL-2407 Satellite-Synchronized Clock, or SEL-2488 Satellite-Synchronized Network Clock.

Clock and Display for Control Rooms—Ensure accurate event logging for control rooms with the SEL-2404 Satellite-Synchronized Clock's large 76 mm (3.0 in) LED display, visible in all lighting conditions.

Accurate Time Synchronization—Provide timing signals to phasor measurement units (PMUs) as part of a synchronized phasor measurement and control (synchrophasor) system.

Clock and Display for Substations—Apply with relays, Sequential Events Recorders, and information processors in applications requiring accurate time and highly visible time indication. Four demodulated IRIG-B outputs with an average accuracy of ±100 ns (±500 ns peak) meet requirements for existing and future timing applications.

Details

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.

Reliable—Exceeds IEEE and IEC Relay Standards
Apply in harsh environments. Exceeds IEEE C37.90 and IEC 60255 protective relay standards. Accurate operation from –40° to +80°C.

Big and Bright
See time from 200 feet away, even in direct sunlight, with bright, easy-to-read, three-inch LED digits.

Low Price
Get an innovative satellite-synchronized clock, with SEL service and support, at a great price.

Simple Operation
Program time offsets and output formats with easy-to-operate control (DIP) switches mounted on the rear panel. Make settings without removing the SEL-2404 from its mounting location.

SEL Releases New SEL-9524 GNSS Antenna
SEL is now offering a new antenna, as both an ordering option, and as an accessory for SEL satellite-synchronized clocks. The SEL-9524 is a ruggedized GNSS antenna manufactured in our Pullman, Washington, facility. It includes a dual-constellation GPS/GLONASS option or a GPS-only option. The antenna operates using 3.5–6 V and includes an LED for diagnostic information. It has a strong gain of greater than 40 dB.

SEL recommends pairing the SEL-2407 and SEL-2404 with the SEL-9524A GPS GNSS Antenna. The SEL-9524B GPS/GLONASS GNSS Antenna is to be used with the SEL-2488. The legacy 235-0113 and 235-0103 Bullet Antennas are still available in limited quantities.
