The document describes the features and characteristics of the 3B17 series modules, including signal isolation, amplification, and filtering functions for 4, 5, or 6-wire Linear Variable Displacement Transformers (LVDTs) and Rotary Variable Displacement Transformers (RVDT). The module provides an AC excitation voltage of 1V rms to 5V rms at frequencies between 1 kHz and 10 kHz, and can withstand 130V rms at the input screw-terminals. The 3B17 series modules are mix-and-match and hot swappable, suitable for industrial signal amplification, isolation, and filtering applications.
The 3B17 is a wide‑bandwidth single‑channel signal‑conditioning module that isolates, amplifies, and filters signals from 4‑, 5‑, or 6‑wire Linear Variable Displacement Transformers (LVDTs) and Rotary Variable Displacement Transformers (RVDTs). It provides an AC excitation voltage of 1 V rms to 5 V rms over a frequency range of 1 kHz to 10 kHz and offers dual high‑level analog outputs (voltage and current).
The module is hot‑swappable, mix‑and‑match compatible with other 3B series modules, and includes input protection up to 130 V rms, +1500 V peak isolation, and accuracy of ±0.1 % of span. Mechanical dimensions are 3.15" × 3.395" × 0.775" and it operates from –28 °C to +85 °C.
