3B47 Datasheet | Analog Devices

FEATURES Interfaces, amplifies, filters, isolates, & linearizes analog input voltages from a J, K, T, E, R, S or B-type thermocouple Thermocouple input signal is internally linearized High accuracy internal cold junction pensation. Module provides +1500 V peak of galvanic transformerbased isolation with a mon mode rejection (CMR) of 160 d B @ 50/60 Hz and a normal mode rejection (NMR) of 60 d B @ 50/60 Hz. All 3B47 series modules are mix-and-match and Hot Swappable. FUNCTIONAL BLOCK DIAGRAM Figure 1. 3B47 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. PRODUCT OVERVIEW The Analog Devices 3B Series Signal Conditioning Subsystem is Data Shee designed to easily handle signal conditioning problems in The 3B Series of Signal Conditioning I/o Subsystems provide a measurement and control applications. Some typical uses are in . low-cost, versatile method of transferring analog transducer microputer-based data acquisition systems, programmable signals to a data acquisition, monitoring or control system controllers, analog recorders, dedicated control systems, and any without the inherent noise, non-linearity, drift and extraneous other applications where monitoring of temperature, pressure, voltages. The modules are designed to directly accept analog flow and analog signals are required. Since each input module signals from Thermocouples, RTD’s, AC and DC Strain Gages, features two simultaneous outputs, the voltage output can be Torque Transducers, Frequency Transducers, LVDTs, millivolt used to provide an input to a microprocessor-based data or process current signals. The modules amplify, isolate, acquisition or control system while...
