DTR-NET

DIGITAL INTERFACE
FOR LOAD CELLS 

The DTRNET series instruments are microprocessor interface units for strain gauge load cells. A simple installation and immediate use make these products suitable for the specific requirements of industrial plants. Available with interfaces Fieldbus Profibus-DP® o Profinet®.

GENERAL CHARACTERISTICS

  • Durable metal Housing and Din rail mounting
  • Communication bus Profinet® o Profibus-DP®
  • Compatible with remote display Logic DLC3-RD o BEKA® (ATEX Zona 1)
  • Meets the EMC provisions of Directive 2004/108/CE and has been tested according to the harmonized standard EN 61000-4 ed EN 61000-6

Galvanic isolation through DC / DC converter between 24Vdc power supply, load cell, fieldbus and remote display for maximum noise attenuation. The instrument is electrically calibrated at the factory.

PROFIBUS-DP® slave interface (up to 12 Mbit / s): allows easy connection to PLC / PC up to 124 units on a single link.

PROFINET® slave interface (10/100 Mbit / s) with integrated Ethernet switch for cascade connection.
