Get Data Sheet

VCL-3045 is synchronized by an NTP Server and can be used as a time source for equipment that requires IRIG-B inputs for time-of-day synchronization.

Isolates and Secures.
Isolates the time-synchronization input of IEDs such as the Protection Relays and RTUs from the IP network.
The IRIG-B interface remains the only connection between the VCL-3045 and the Protection Relay / RTUs, thereby providing maximum security and isolation to IEDs an IP network from external hostile elements.
Enables flexibility in installation
Enables secure and compact installations
Increases reliability, availability and accuracy.
Provides flexibility of usage and enhanced efficiency allowing for maximum utilization of the available resources.

Features and Benefits:

May be synchronized from a local or public NTP server
Provides 4 Unmodulated IRIG-B output (BNC, RS232, RS485 / RS422 ) options
Built-in real-time clock / real-time logging maintains a history of all events.
Serial Management Interface (USB) for local access.
Remote access over Telnet and SSH. Allows the user to access and carry out maintenance
Password Controlled Access. Maintains a complete log of all logins.
