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-8B31 module isolates, filters and amplifies a voltage input signal and provides an analog voltage output.
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-8B31 modules provides protection against accidental connection of power-line voltages up to 240VAC.
Isolation is provided by optical coupling to suppress transmission of common mode spikes or surges. The module is powered from +5 VDC, ±5%.
The modules are designed for installation in Class I, Division 2 hazardous locations and have a high level of immunity to environmental noise.
