8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 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.

The signal filtering is accomplished with a 3-pole filter optimized for time and frequency response which provides 60dB per decade of normal-mode rejection above 100Hz. A special input circuit on the 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.

The 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.
