8B49
Voltage Output Modules
Description
8B modules are an optimal solution for monitoring real-world process signals
and providing high-level signals to a data acquisition system. Each 8B49 module
accepts an input signal from a non-isolated source, then isolates, filters and
converts the signal to a high level process voltage output.
Signal filtering is accomplished with a four-pole filter optimized for time and
frequency response which provides 80dB per decade of normal-mode-
rejection above 100Hz. One pole of this filter is on the system side and the other
three are on the isolated field side.
A special output circuit in the 8B49 module provides protection against accidental
connection of power-line voltages up to 40VAC continuous. Clamp circuits on
the I/O and power terminals protect against harmful transients.
The modules are designed for installation in Class I, Division 2 hazardous
locations and have a high level of immunity to environmental noise.
