The 8B-33-01 Isolated True RMS Input Module from Dataforth Corporation is designed to provide a single channel of AC input, converting it to a True RMS DC value. It supports input signal ranges from 0mV to 100mV and outputs a standard process voltage of 0 to 5VDC. The module is suitable for standard operation with frequencies ranging from 45Hz to 1000Hz, with an extended range up to 10kHz. This module features a 1500Vrms transformer isolation, ensuring protection against common-mode spikes and surges. It is equipped with special input circuits that protect against accidental connections to power-line voltages up to 350VAC and transient events as defined by ANSI/IEEE C37.90.1. The accuracy of the module is ¬±0.25% at factory calibration, and it has a common mode rejection ratio (CMR) of 120dB. The 8B-33-01 is compliant with RoHS III and is suitable for use in high-vibration industrial environments. It operates within a temperature range of -40¬?C to +85¬?C and has a compact size of 1.11,Äù x 1.65,Äù x 0.40,Äù. This module is UL/cUL listed and CE compliant, making it a reliable choice for embedded applications in various industrial settings.
Each 8B33 True RMS input module provides a single channel of AC input which is converted to its True RMS DC value, filtered, isolated, amplified, and converted to a standard process voltage output (see Block Diagram).The field voltage or current input signal is processed through a pre-amplifier and RMS converter on the field side of the isolation barrier. The converted DC signal is then chopped by a proprietary chopper circuit and transferred across the transformer isolation barrier, suppressing transmission of common mode spikes and surges. The computer side circuitry reconstructs, filters, and converts the signal to an industry standard output of 0 to 5VDC.Special input circuits provide protection against accidental connection of power line voltages up to 350VAC and against transient events defined by ANSI/IEEE C37.90.1.
