3B37

www.DataSheet4U.com Isolated, Thermocouple Input 3B37 FEATURES Interfaces, amplifies, & filters input voltages from a J, K, T, E, R, S, or B-type thermocouple. High accuracy internal cold junction compensation. Module provides simultaneous precision voltage and current outputs. Current output withstands 130V rms without damage. All 3B37 series modules are mix-and-match and Hot Swappable. FUNCTIONAL BLOCK DIAGRAM APPLICATIONS Industrial signal conditioning Industrial signal isolation Industrial signal filtering Figure 1. 3B37 Functional Block Diagram PRODUCT OVERVIEW The 3B Series of Signal Conditioning I/o Subsystems provide a low-cost, versatile method of transferring analog transducer signals to a data acquisition, monitoring or control system without the inherent noise, non-linearity, drift and extraneous voltages. The modules are designed to directly accept analog signals from Thermocouples, RTD’s, AC and DC Strain Gages, Torque Transducers, Frequency Transducers, LVDTs, millivolt or process current signals. The modules amplify, isolate, linearize and convert the transducer output signals to standardized analog inputs for high-level analog I/O subsystems. The 3B Series Subsystem consists of a 10” relay rack with universal mounting backplane and a family of plug-in (up to 16 per rack) input and output signal conditioning modules. Eight and four channel backplanes are also available. Each backplane incorporates screw terminals for sensor inputs and current outputs and ...
