Fibre Input (Order Code D2)
•
Takes a copper or Fibre based pulse or IRIG-B signal as input.
•
Provides isolated Fibre, TTL, RS232 and RS422 as standard outputs
•
Provides isolated AM IRIG-B as an optional output.
HV MOSFET (Order code D3)
•
Takes a Copper or Fibre based pulse or IRIG-B signal as input.
•
Provides isolated Fibre and HV MOSFET output as standard.
For the HV MOSFET wiring use a slow blow with a 300V dc voltage rating fuse no
greater than 200mA.
Note: For the HV MOSFET ITR option high voltage may be present on the HV terminals as
well as the PWR input terminals. For this reason, there is a DUAL SUPPLY label affixed to
warn of this as pictured above.
All three configurations can be ordered with a low, medium or high voltage power supply
option with typical power drain of 5W max. The power to I/O isolation is 2kV.
