  • Enhanced comparator functions
    In addition to a simple comparison of the upper/lower limit, the AD-4532B is equipped with a 2D comparator function that shifts between the upper/lower limit in five levels using a time control or an external signal.
  • 2D (5-level) comparator function
    This function makes it possible to determine the acceptability of the total result by performing a sequential comparison while shifting between the upper/lower limit in five levels using a time axis or an external input (trigger).
    It is ideal for use in measurements, such as a press-in operation, which require changes in the comparison
    value as time elapses.
    The five comparators can also be used individually.

  • High-speed A/D*1 and D/A*2 conversion function at 2000 times/sec.
    *1 Analog-to-digital conversion *2 Digital-to-analog conversion
  • Calibration without an actual load
    The digital span calibration function makes it possible to perform a calibration by entering the rated output (mV/V) of the sensor using the numeric keys. This function is useful when an actual load cannot be applied.
  • Latching function
    The display, the comparator output and the D/A voltage output can be latched (data output hold).
  • Relay output with a long-life MOSFET relay
  • Chatter-prevention function
    If bouncing of the comparator value occurs repeatedly near the upper/lower limit, a heavy burden will be placed on the relay circuit and other parts. To prevent this, the AD-4532B has a function to set the hysteresis width and time.

  • Hold Function
    The hold mode can be activated using the front panel key,a Modbus-RTU, or the external input terminal on the rear
    panel.

     

  • Wide variety of data input/output
    The AD-4532B comes equipped with an analog amplifier voltage output (±10V), a D/A analog voltage output (±10V), a comparator output and a Modbus-RTU input/output. In addition, we offer an optional BCD output, RS-232C input/output, D/A analog voltage/current output (±10V / 4 to 20mA) and Ethernet. The upper/lower limit setting, the zero compensation function and the hold function can be executed via Modbus-RTU.
