synchronized clock / GPS / PTP / IEEE 1588 synchronized clock / GPS / PTP / IEEE 1588 - 1205D


  • Options:

    synchronized, GPS, PTP, IEEE 1588


Model 1205D delivers better than 40 ns typical accuracy and includes the most highly sought after features in a precision time clock as standard plus enhanced performance and security (EPS) in a DIN rail mounted package.

The standard holdover oscillator maintains accuracy of 1 ms/day when not tracking satellites. In addition to enhanced performance, Arbiter Systems' new EPS technology includes GNSS anti-spoofing and secure password-protected and encrypted configuration interface providing robust, reliable synchronization to help comply with latest NERC-CIP requirements.

The Model 1205D timing signals are available via the three Ethernet ports and the thirty-two pin terminal block. The three 10/100 Ethernet ports (copper standard, fiber optional) provide status, configuration as well as network timing supporting the NTP, SNTP, PTP (IEEE 1588Power Profile supported), SNMP, ICMP, TCP, SSH, SSL, HTTP, HTTPS and DHCP protocols. The thirty-two pin terminal block provides access to the Model 1205D standard inputs, outputs and legacy communication ports. Two inputs, an event timer and a frequency monitor, are included along with six Programmable Pulse outputs, a modulated IRIG-B output, a FET output, relay contacts, two RS-232 ports and a RS- 422/485 port (transmit only).

The Model 1205D standard power supply is a 13.5 Vdc to 26.4 Vdc supply with secure terminal strip inlets and surge-withstand capability. The surge-withstand network is designed to meet ANSI/IEEE C37.90-1 and IEC 61000-4 specifications. Also included is a built-in lightning arrestor and rear panel ground plate to protect against secondary lightning strikes and other antenna coupled surges.
