The Model 10881A Fiber-Optic to Logic Adapter allows transmission of a digital signal over several kilometers and upon receiving, for the conversion to a + 5 V CMOS logic levl output signal. One optical signal is received and simultaneously sent as an electrical signal on two separate, individually-buffered BNC or Pluggable Terminal (shown above) output connectors.

The signal logic level is HI whenever the optical signal is ON. Whenever optical data is received the Data LED Iluminates (flashes).

  • Support for long distance transmission (several kilometers)
  • Can be used with any Arbiter GPS satellite controlled clock
  • Select BNC or Pluggable Terminal output connectors
  • Can be used with DIN Rail mounting brackets

Ordering checklist:

  • 10881A
    • Output connector style (BNC or Pluggable Terminal Strip)
    • DIN Rail Mounting?
    • Power Supply (Many to choose from. Please look under the Accessories tab.
      • DIN Rail Mounting? Not all power supplies have DIN Rail mounting available.
