  • Protective Separation up to 300 V AC/DC, test voltage 3 kV
  • Easy configurable via DIP switches or Modbus interface
  • Freely scalable up to 247 measuring inputs in one Modbus segment
  • Extremly slim, only 6.2 mm installation width
  • Made in Germany
  • 5 Years Warranty

The Modbus Standard Signal AI Module is used for electrical isolated conversion of unipolar standard voltage and current signals. All parameter can be set via Modbus RTU Interface. A subset of the most common settings is available via DIP switches.

The measuring value can be read over the Modbus RTU (RS485) interface.

The 2-way isolation guarantees reliable decoupling of the sensor circuit from the processing circuit and the auxiliary power circuit. Auxiliary power and Modbus RTU can be connected via the connection terminals or via the In-Rail-Bus connector (see accessories).
