Meet Riotech’s x-VII™

Call 817.886.8210 to incorporate the x-VIITM Vital Input Isolator Module into your highway-rail grade crossing applications today.

Key Features

  • Supports 4 isolated channels

  • Flexible power source accommodates both DC only and AC supported input file rack

  • External operational test switches

  • Front and rear facing I/O ports

  • Installs in existing input file rack

  • Provides isolated conversion from railroad circuitry to traffic signal logic levels

  • Dual voltage 24 V dc or 120 V ac with self-supplied 24 V dc power supply for standalone operation

  • Inputs are non-polar for easy system wiring

  • Internal self-checks to guarantee logic functionality

  • Each isolated channel provides an output referenced to controller logic ground and an additional

  • isolated output referenced to isolated ground

  • Signals can be inverted with use of configuration jumpers
