| DI-8B42 2-Wire Transmitter
Interface Module |
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-8B42 module provides
power to a current transmitter, then isolates, filters
and amplifies the resulting 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
60dB per decade of normal-moderejection above 100Hz. 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-8B42 module provides
protection against accidental connection of power-line
voltages up to 40VAC. 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.
