Analog Output

The analog output from the 

iQUBE

 can be connected to the analog signal inputs of any weight indicator that can

be read 0-30mV (0-20mA) referenced to ground (see Figure 2-12). Analog output from the 

iQUBE

 requires that a

digital-to-analog (DAC) card be installed on the 

iQUBE

 core module. Both voltage- and current-based DAC

cards are available. See Section 2.14.1 on page 15 for more information about DAC card installation.

NOTE:

 Analog output wiring 

must include ground wire

 (pin 3 on connector J9 on the 

iQUBE

 connector board).

Figure 2-12.
