  • Page 5: Device Description

    The WDT11 amplifier is designed for operation with load cells (4 or 6 wires without build-in electronics). It enables processing of sensor signals into current signal 4-20mA (or voltage signal 0-10 V) and digital (RS485). Build-in RS485 interface with MODBUS protocol allows direct communication one or several modules with PLC or HMI.

    Yellow Green Table. 1 Wires color description for sensors from WObit’s offer. CAUTION – it is possible that colors of signals may change. Tara input / tara button WDT1 is equipped with TARA input which tare measurement after giving voltage in range 5..24VDC (regarding to GND) during min 100 ms.
  • Page 8: Analog Output 4-20 Ma/0-10 V

    2.5 Analog output 4-20 mA/0-10 V WDT11 depend on version is equipped with current output (4-20mA) or voltage output 0-10 V which process force value into proper current/voltage value. Output analog value can be calculated to measured force according to settings.
  • Page 9: Device Configuration

    3. Device configuration 3.1 Connection via USB USB connector is used for communication with WDT11-PC program. After connecting to PC and starting WDT11-PC program there should appear information about connection. Installation of USB port drivers isn’t required. In case While no connection please disconnect USB wait and try to reconnect.
  • Page 10: Configuration Of 4-20 Ma / 0-10 V Output

    Filtration level = 4, Frequency = 50/sec. Device response time = (4 + 1) x 1000/50 = 100 ms. WDT11 will present complete value of measured force after 100ms since it starts. 3.3 Configuration of 4-20 mA / 0-10 V output Depend on device version is available current 4-20 mA or voltage 0-10 V signal which can be freely calibrated regarding to measured force value.
  • Page 11: Rs485 Modbus Configuration

    4. RS485 MODBUS communication RS485 can be used for communication with PLC, HMI or other device using MODBUS-RTU protocol. The RS485 terminal at WDT11 isn’t galvanically insulated so please provide the same ground electric potential for WDT11 and master device (common GND signal).
