Data sheet

Overview

Built by Power Professionals, For Power Professionals Model 1205B/C 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). 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 1205B/C timing signals are available via the three Ethernet ports, the thirty-two pin terminal block and from the three available option slots. 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 1205B/C 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 1205B/C is available with two front panel configurations (see photos and Key Features tab). Each product includes the GNSS antenna and cable, a terminal power strip, and a rack mount kit, all backed by a Five Year Limited Warranty to the original owner/purchaser.
