Description

WObit • Signal conditioner for strain gauge, 4-20mA output, RS485 interface

WDT11-I is a universal transducer for strain gauge force sensors. Thanks to the digital converter, the system allows you to precisely measure the force and convert it into 4-20mA and a digital (RS485) signal.

The built-in RS485 interface with the MODBUS protocol allows for direct communication to one or more modules with a PLC or HMI panel. It is possible to connect up to 32 modules on one bus.

The configuration of the module is done via the USB port and the associated software, In addition to the device settings, the software also allows you to view the current measurement values.

Features:

  • Measurement from a strain gauge (4 or 6 wire)
  • Converting values to selected units
  • Configurable sampling rate and signal filtering
  • Analog output: (0)4-20 mA
  • RS485 interface with MODBUS protocol
  • USB connector for device configuration
  • Built-in button and external tare connector
  • LED status indication
  • Power supply for the device 12-24 VDC
  • Mounting on a DIN rail or brackets
