SEL-2488 Satellite-Synchronized Network Clock
-
NG # 001427-HW-SEL-027
Manufactured by:
The SEL-2488 receives Global Navigation Satellite System (GNSS) time signals and distributes precise time via multiple timing outputs, including IRIG-B, the Network Time Protocol (NTP), the Precision Time Protocol (PTP), 10 MHz frequency, and 1 pulse per second (PPS).
Specification
- Simple Authentication
- GNSS Vulnerability Mitigation
- Cable Delay Compensation
- Easy and Secure Commissioning
- Timekeeping Compliance for Public Service Answering Points (PSAPs)
- Land Mobile Radio (LMR) Time Synchronization
Description
With an optional upgrade, the SEL-2488 can serve as a PTP grandmaster clock, as defined by IEEE 1588-2008. It provides Parallel Redundancy Protocol (PRP) support as a Dual-Attached Node (DAN) device for PTP and NTP time distribution. The advanced capabilities of the SEL-2488 make it well-suited for critical infrastructure networks like emergency communications systems, for substations with multiple time synchronization requirements, and for demanding power utility applications—like synchrophasors, Sampled Values, and traveling-wave fault locating.
