DAD 141.1

Digital Amplifier + Logic IOs + Analog Output + Type Approval DIN (TS35) Rail Mount


The All-in-One DAD 141.1 is a universal device for any weighing, filling or loss-in-weight operation and for force measurements. The DAD 141.1 is a digital load cell amplifier with serial RS422/RS485, Ethernet and analog output for remote indication. The DAD 141.1 performs static or semi-dynamic measurements in hostile, industrial environments, where reliability, stability and security are of major importance.

Product highlights

  • Provides both, digital and analog data from weighing and measuring operations.
    Serial port RS422/485 and Ethernet port.
    Modbus RTU and Modbus TCP on board.
    Two programmable logic inputs and three programmable logic outputs permit remote operations.
    Set-up and calibration are extremely simple; the DAD 141.1 is designed to enable field calibration directly from known load cell sensitivities (eCal) or just by test weight(s).
    Simple to configure; straight forward set-up and calibration via the front panel keyboard or from any PC with OS Windows XP/Vista/7/8 using the DOP4 software.
    Permits live range down to a few percent of the load cells rating, with virtually no zero drift.
    The LP input filter and the jump function can be set to meet most requirements for speed.
    The display, the analog current or voltage output and the full duplex interface provide for a full communication of results.
