INDUSTRIAL TOUGHNESS AND PROVEN RELIABILITY

RS-485 INDUSTRIAL STANDARD OF RELIABILITY

ULTRA LOW POWER PERFORMANCE

MODBUS EASE-OF-USE

 

All BARANI sensors use MODBUS protocol to communicate over their RS-485 communication interface.

OTHER AVAILABLE SENSOR OUTPUTS

ANALOG

  • Pulse (Square Wave),
  • 0-10V
  • 4-20mA

DIGITAL

  • RS-485 with MODBUS ASCII & RTU
  • RS-422 with MODBUS ASCII & RTU
  • RS-232 with MODBUS ASCII & RTU

RS-485 ADVANTAGES over SDI-12

  • RS485 sensors are able to achieve much higher data throughput than SDI-12
  • RS485 sensors are able to have strong lightning, transient and ESD protection
  • Many RS485 sensors can easily be daisy chained together without communication interference and latency problems.
  • RS485 sensors can implement industry standard and proven MODBUS protocol designed for robust communication in harsh environments.
  • Today's RS485 sensors are able to achieve very low sub-milliampere (mA) power consumption which is critical for wireless weather stations, smart city applications, IoT and other sensor systems.

MODBUS ADVANTAGES over other protocols

  • Proven reliability over decades of use in harsh industrial environments.
  • Simple Request / Response architecture
  • Built in data checks to eliminate false data packets. (Checksum)
