The ANR-271C is a 3G Modbus, TCP, and UDP cellular RTU with various interfaces for a wide range 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 capability from -40°C to +80°C and 0% to 100% relative humidity.
  • 4 integrated relay ports. Activation can be automatic or manual.
  • Internal battery with a runtime of at least 4 hours of continuous use.

The Above-Net ANR-271C is compatible with the Above-Net Bridgemeter IoT monitoring system and offers complete control over remote configuration and parameter monitoring.
