Input Modules |
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-8B38 module isolates,
filters and amplifies a full-bridge strain gage input
signal and provides an analog voltage output.
The 8B38 can interface to tranducers with a nominal resistance
of 100O to 10kO depending upon the model. Bridge excitation
is provided from the module with a stable 10.00V or 3.33V
source. Full scale sensitivities of 2mV/V and 3mV/V are
offered as standard.
Signal filtering is accomplished with a five-pole filter
optimized for time and frequency response which provides
100dB per decade of normal-moderejection above the filter
cutoff frequency. One pole of this filter is on the field
side of the isolation barrier for anti-aliasing, and the
other four are on the system side.
A special input circuit on the DI-8B38 module provides
protection against accidental connection of power-line
voltages up to 240VAC. Clamp circuits on the I/O and power
terminals protect against harmful transients.
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.
