Reliable—Exceeds IEEE and IEC Relay Standards

Apply in harsh environments, including outdoor control enclosures. Exceeds IEEE C37.90 and IEC 60255 protective relay standards for robustness. 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 ns accuracy meet requirements for existing and future timing applications.

Low Price—High Performance

Ideal for small substations or situations where a high-quality time signal is required.

Control Applications

Use the contact output as a precision trigger for time-coordinated testing, event initiation, or other control functions.
