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.

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.
