Product Highlights
Each DI-5B32 current input module provides a single channel
of analog input which is filtered, isolated, amplified,
and converted to a high level analog voltage output. This
voltage output is logic-switch controlled, allowing these
modules to share a common analog bus without the requirement
of external multiplexers.
TheDI-5B32 module is designed with a completely isolated
computer side circuit which can be floated to ±50V
from power common (pin 16). This complete isolation means
that no connection is required between I/O common and
power common for proper operation of the output switch.
A precision 20x current conversion resistor is supplied
with each DI-5B32 module.
Signal filtering is accomplished with a six-pole filter,
which provides 95dB of normal-mode-rejection at 60Hz and
90dB of rejection at 50Hz. Two poles of this filter are
on the field side of the isolation barrier, and the other
four are on the computer side.
After the initial field-side filtering, the input signal
is chopped by a proprietary chopper circuit. Isolation
is provided by transformer coupling, again using a proprietary
technique to suppress transmission of common mode spikes
or surges. The module is powered from +5VDC, ±5%.
A special input circuit on the DI-5B32 provides protection
against accidental connection of power-line voltages up
to 240VAC.
