Isolated Timing Repeater Fiber

Key Features:

Isolated Timing Repeater(Low voltage fiber)

• Extend the distance of an IRIG-B or Pulse signal
• Provide isolation between A & B Protection Systems or between IEDs
• Converts a TTL signal from copper to fiber / fiber to copper
• Converts a TTL signal to a digital High Voltage MOSFET signal
• Reduces wiring to panels of equipment
