Chapter 3 Analog Output Module AH04DA/AH08DA (X2, Y2) (10, 10.1 V) Original signals Signals after the calibration Digital value (X) Voltage (Y) (X: Digital value; Y: Analog signal) 3. Scale range The analog output mode of a channel has a corresponding digital range. Digital values correspond to analog outputs sent by a module. For example, if the analog range is -10 V~10 V and the digital range is -10.0~10.0, the digital values -10.0~10.0 correspond to the analog values -10 V~10 V. Analog value 10 V Rated output range -10 V 10.0 -10.0 Digital value 4. Retaining an output Scale range When a module stops running, a signal sent by the module is retained. 3-9 10.1 V 10 V (X1, Y1) (0, 0 V) -10 V
