Isolated Timing Distributor

Key Features:

The Isolated Timing Distributor is designed to provids a simple method to distribute the unmodulated IRIG-B between rooms or of substation panels while maintaining electrical isolation.

• Extend the distance of an IRIG-B or Pulse signal
• Provide isolation between A & B Protection Systems or between IEDs
• Reduces wiring to panels of equipment
