FiberPlex SID-3232 3 Channel TIA-232 TEMPEST data scrubber

The SID-3232 is a 3 Channel TIA-232 Serial Isolation Device designed for Black/Red network applications.

The SID-3232 will isolate three RS-232 lines between a BLACK and a RED communications environment at data rates up to 128 kbps. The two interfaces will be electrically isolated, either by optical coupling for the data lines, or transformer coupling for isolated DC power to operate the RED side interface of the device. The device may also be used as an RS-232 repeater, re-driving the lines to extend distance. The inputs and outputs are fault tolerant to ±70 volt levels. Input power may be from a broad range of standard DC supply voltages.

SID-3232 applications

  • Complete signal isolation between ends
  • High voltage fault tolerant RS-232 inputs and outputs (70 VDC)
  • Data rates may differ between circuits, DC up to 128 kbps
  • IP68 rated enclosure
