SensorLex8B39

Current Output Modules, Bandwidth 100 Hz

8B modules are an optimal solution for monitoring real-world process signals and providing high-level signals to a data acquisition system. Each 8B39 module accepts an input signal from a non-isolated source, then isolates, filters, and converts the signal to an analog process current output.

Signal filtering is accomplished with a 3-pole filter optimized for time and frequency response which provides 60 dB per decade of normal-mode rejection above 100 Hz. One pole of this filter is on the system side and the other two are on the isolated field side.

A special output circuit in the 8B39 module provides protection against acciden-tal connection of power-line voltages up to 40 VAC 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.
