Signal filtering is accomplished with a pole filter optimi ed for time and frequency response which provides 70dB of normal-mode rejection at H . 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 8B30 and 8B31 modules 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 transformer 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.
