The Isolated Timing Distributor provides a simple method to reticulate unmodulated IRIG-B between rooms and/or rows of substation panels while maintaining electrical isolation. The device receives TTL HCMOS or fiber signals and regenerates simultaneously on four channels over either TTL or fiber. Balanced and isolated inputs and outputs provide excellent noise immunity.
Key Features:
- 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
Input/Output Signals:
- Copper input
- Fiber input
- Fiber output
- TTL output
