Remote Fiber-Optic Module (PN 77789)
The optional remote fiber-optic module provides optically isolated digital-to-analog (DAC) conversion of digital
data received from the
iQUBE
. The analog output from the module can be connected to the analog (load cell)
signal input of a standard weight indicator that can read 0-30mV (0-20mA) referenced to ground (see
Figure 2-10).
This option requires that the
iQUBE
be fitted with its internal fiber-optic card (see Figure 2-9 on page 11); both
voltage- and current-based DAC cards available for the remote fiber-optic module.

Figure 2-11 shows connector locations on the remote
fiber-optic interface.
