DESCRIPTION
DI-8B modules are an optimal solution
for monitoring real-world process signals
and providing high level signals to a data
acquisition system. Each DI-8B32 module
isolates, filters and amplifies a process
current input signal and provides an analog
voltage output.
Current to voltage conversion is accom-
plished internal to the module to ensure
high accuracy.
Signal filtering is accomplished with a
three-pole filter optimized for time and
frequency response which provides 70dB
of normal-mode-rejection at 60Hz.
One pole of this filter is on the field side of
the isolation barrier for anti-aliasing, and
the other two are on the system side.
A special input circuit on the 8B32 module
provides protection against accidental
connection of power-line voltages up to
30VAC.
Isolation is provided by optical coupling
to suppress transmission of common mode
spikes or surges. The module is powered
from +5VDC, ±5%.
The modules are designed for installation
in Class I, Division 2 hazardous locations
and have a high level of immunity to envi-
ronmental noise.
