VCL-2705, GPS Receiver and Time Distribution Unit

The VCL-2705 GPS Receiver and Time Distribution Unit is a compact and cost-effective solution to provide 3 commonly used types of IRIG-B outputs to make it suitable in any application which requires an IRIG-B time input. This solution is designed to work in harsh environments including outdoor control enclosures. Meets IEEE C37.90 and IEC 61850-3 standard for robustness. Suitable for utility applications including relay event correlation and other high-accuracy timing requirements. Un-Modulated IRIG-B outputs with ±400ns accuracy to meet the requirements for existing and future timing applications.
