The ANR-271C is a 3G Modbus, TCP and UDP cellular RTU with multiple interfaces for a multitude of reading and monitoring applications.

It has:

  • 4 analog inputs that can be configured as 0-5V or 0-20mA or 4-20mA;
  • 4 digital inputs that can operate as normally closed or open positions or even as a pulse counter.
  • Input for H/T temperature and humidity sensors with measurement capacity from -40C to +80C and 0% to 100% relative humidity.
  • 4 integrated relay ports. Activation can be performed automatically or manually.
  • Internal battery with autonomy of at least 4 hours of continuous use.

Above-Net 's ANR-271C is compatible with Above-Net 's Bridgemeter IoT monitoring system and provides full control over remote parameter configuration and monitoring.
