IR-300
NTP to IRIG-B Converter

KEY FEATURES Data Sheet

Overview

The IR-300, NTP to IRIG-B Converter provides time synchronization to terminal equipment which requires precise time synchronization through an IRIG-B interface using an NTP time source. The DIN rail chassis is ideal for deployment where space is at a premium and for installations where it is not possible to install external GPS antennas.

The IR-300 NTP to IRIG-B Converter allows the user to assign up to 3 NTP Servers for redundant time synchronization. It selects the best available NTP Server based on criteria such as stratum level, jitter and wander, which ensures that the terminal equipment always remains synchronized to the best available time source.

The IR-300 also helps isolate the terminal equipment from the perils of hacking and unlawful intrusions that are possible on an IP network. It is available in 3 types of IRIG-B interface options which include 50 Ohm BNC connectors, RS232 twisted pair and RS422/RS485 5V/3V differential output (full duplex).

Our IR-300 is available in a small form factor DIN Rail chassis.
