ITR

The Isolated Timing Repeater (previously known as the MOFR) is a compact DIN rail mountable signal repeater that performs a number of tasks, including converting time sync signals , boosting signal strengths and converting one type of signal to another. The Isolated Timing Repeater is completely electrically isolated and it will provide your IEDs (Intelligent Electronic Devices) with an additional layer of electrical protection.

Key Features:

• 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

Input/Output Signals:

• Copper to fiber
• Fiber to copper
• RS232 output
• RS422 output
• Fiber output
• TTL output
• HV MOSFET output
• Optional AM IRIG-B output
