Product Highlights
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 accomplished 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 DI-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 environmental noise.
