3 Channel TIA-232 Serial Isolation Device

Model #: SID-3232

SID-3232_500.png

The SID-3232 will isolate three (3) RS-232 lines between a BLACK and a RED communications environment at data rates up to 64Kb/s. 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 inputs and outputs are fault tolerant to +/70 volt levels. Input power may be from a broad range of standard DC supply voltages. The device may also be used as an RS232 repeater, re-driving the lines to extend distance.

  • Complete signal isolation between ends
  • High voltage fault tolerant RS232 inputs and outputs (+/-70 VDC)
  • Data rates may differ between circuits, DC up to 128 kb/s
  • IP68 rated for harsh environments
