11. ANALOG OUTPUT
The AD-4532B has two types of analog output; the analog amplifier output (AAO) that amplifies the
sensor’s analog signals and outputs the amplified signal, and the digital to analog voltage output
(DAV) that processes the measured values from the sensors according to the values set in function
mode, and outputs the processed signal as a voltage after D/A conversion.
These outputs are used to observe the voltage waveform from the sensors by connecting a recorder
to the analog output terminal.
11-1 Analog Amplifier Output (AAO)
Amplifies the sensor’s analog signals 625 times and outputs the amplified signal. The output voltage
range is from –10 V to +10 V. The pass band can be changed in function mode
f-01
.
Output example
When the excitation voltage is 5 V and the sensor rated output is 3.2 mV/V,
the analog output value will be:
Sensor output voltage = 3.2 mV/V x 5 V = 16 mV.
Analog amplifier output voltage = 16 mV x 625
≈
10 V.
Note: The output voltage varies depending on the indicator. Before use, be sure to check
the output values of the sensors.
