GenII RC250 Telemetry receiver


The RC250 is a high performance telemetry receiver designed for use with the standard GenII range of telemetry transmitters, repeaters and accessories. It outputs ModBus RTU or serial data to a connected PC for integration into industry standard PC Software. Such software could include LabVIEW, DASYlab, Wonderware or proprietary software compliant to CFR21 Part 11.

This feature rapidly realises a broad spectrum of applications including:

  • Monitoring and analysis
  • Alarm and control
  • Real time data
  • Profile mapping

For customers in the pharmaceutical sector (e.g. where CFR21 Part11 compliance is required) and in the industrial, construction, storage, research and conservation sectors.
