Citra Wahana Sekar Buana


Timing and Frequency

  • Accuracy < ±500 ns typical
  • Unmodulated IRIG-B and 1 PPS included, modulated IRIG-B optional
  • Options include an internal NTP server, High Drive IRIG-B outputs, One Form C (SPDT) fail-safe locked relay, and Power System Time, Frequency and Phase Monitor

Versions A/B/C offer various interface options (see photos):

  • 1093A supports two LEDs for monitoring operating status.
  • 1093B adds to the LEDs an LCD display and keypad, providing easy access to setup and system status information.
  • 1093C includes both the operating status LEDs, the LCD display and keypad, and includes a large LED time display.
  • IEEE C37.118 compliant for Synchrophasor use.


Model 1093A/B/C delivers better than 500 ns accuracy and includes the most highly sought after features in a precision time clock as standard.

With two terminal strip outputs providing unmodulated IRIG-B and 1 PPS signals, the 1093 is capable of driving multiple loads in parallel. An optional modulated IRIG-B port is available adding greater flexibility.

Like other Arbiter clock models, various options are available to add features such as NTP (Network Time Protocol) support, four additional configurable outputs, high drive IRIG-B outputs, power system time, frequency, and Phase Monitor functions, one Form C (SPDT) fail-safe, LOCKED relay that is compatible with 129 Vdc digital fault recorder inputs; plus many more.

Versions A/B/C offer various interface options (see photos and Key Features tab). Each product includes the GPS antenna and cable, an appropriate power inlet and power cord, a rack mount kit and an operations manual, all backed by a Limited Lifetime Warranty.

Model 1093A/B/C is available with three front panel configurations. See photos and Key Features tab for more information.
