3B20 Datasheet | Analog Devices

AC Strain Gage, Torque Transducer Input 3B20 Features Interfaces, amplifies, & filters signals from 4-arm AC bridge transducer signals ranging between 1.5m V rms & 150m V rms. Module provides an AC excitation voltage of 2V rms to 10V rms at frequencies between 1k Hz & 10k Hz.. Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 130v rms at its current output terminals without damage. All 3B20 series modules are mix-and-match and Hot Swappable FUNCTIONAL BLOCK DIAGRAM Figure 1. 3B20 Functional Block Diagram APPLICATIONS Industrial signal conditioning Industrial signal isolation Industrial signal filtering Output modules accept 0 to +10V (or +10V) single-ended signals and provide an isolated 4-20 m A (or 0-20 m A) process signal. All modules feature a universal pin-out and may be readily hot-swapped under full power and interchanged without disrupting field wiring. The Analog Devices 3B Series Signal Conditioning Subsystem is designed to easily handle signal conditioning problems in measurement and control applications. Some typical uses are in The 3B Series of Signal Conditioning I/o Subsystems provide a .. microputer-based data acquisition systems, programmable low-cost, versatile method of transferring analog transducer controllers, analog recorders, dedicated control systems, and any signals to a data acquisition, monitoring or control system other applications where monitoring of temperature, pressure, without the inherent noise, non-linearity, drift and extraneous flow and analog signals are required. Since each input module voltages. The modules are designed to directly accept analog Features two simultaneous outputs, the voltage output can be signals from Thermocouples, RTD’s, AC and DC Strain Gages, used to provide an input to a microprocessor-based data Torque Transducers, Frequency Transducers, LVDTs, millivolt acquisition or control system while the current output can be or process current...
