8B33 signal conditioning module

8B33 signal conditioning moduleAnother module in the family of miniature SensorLex 8B isolated analog signal conditioners is the 8B33, designed for measuring True RMS values of input signals. Each 8B33 True RMS input module provides a single channel of AC input, which is converted to its True RMS DC value, then filtered, isolated, amplified, and converted to a standard process voltage or current output. By reducing the dependency on sinusoidal purity, True RMS conversion allows accurate measurement of signals ranging from pulses to complex nonperiodic waveforms. The conversion core circuit used in the 8B33 is similar to those found in high-end digital voltmeters. Like all modules in the SensorLex 8B family, the 8B33 is fully encapsulated and thus able to withstand harsh environmental conditions while providing fully functional Instrument Class performance. The SensorLex 8B is housed in a miniature 1.11” x 1.65” x 0.4” (28.1mm x 41.9mm x 10.2mm) module. The product line includes 19 family groups with a total of 123 different models. Key features and specifications of the 8B33 include: Interfaces to RMS voltage (0-300V) or RMS current (0-1A); compatible with standard current and potential transformers; ±0.25% factory calibrated accuracy; 1500Vrms transformer isolation; and ANSI/IEEE C37.90.1 transient protection. The line is also available in a DIN mount configuration.
