The 8B39-03 is a current output module that accepts a 0V to +5V voltage input and provides a 0-20mA analog current output. It features 1500Vrms isolation, 110dB common-mode rejection, and 100Hz signal bandwidth with a 3-pole filter providing 60dB per decade of normal-mode rejection above 100Hz. The module includes continuous protection against accidental 40VAC power-line connections and transient protection compliant with ANSI/IEEE C37.90.1. It operates over a temperature range of -40°C to +85°C, measures 1.11" x 1.65" x 0.40", and is rated for Class I, Division 2 hazardous locations. Accuracy is ±0.05% of span with ±0.02% linearity. The module is RoHS III compliant, UL/cUL listed, and CE compliant.
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 60dB per decade of normal-mode rejection above 100Hz. 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 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.
