3B User Configured

The 3B Series of analog signal conditioning modules, backplanes and accessories is the most comprehensive and versatile available for product testing and industrial measurement applications. The 3B Series interfaces between real-world analog sensor signals and data acquisition or measurement and control systems. The modules isolate and condition the widest range of I/O sensor and signal types and provide simultaneous high-level voltage and current outputs.

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/0 subsystems. The 3B Series Subsystem consists of a 19" 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 a 26-pin connector for high-level single-ended voltage outputs to the user's equipment.

The input modules feature complete signal conditioning circuitry optimized for specific sensors or analog signals and provide two simultaneous high-level analog outputs: 0 to +10 V (or ±10 V) and 4-20 mA (or 0-20 mA).

Output modules accept 0 to +10 V (or ±10 V) single-ended signals and provide an isolated 4-20 mA (or 0-20 mA) 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 microcomputer-based data acquisition systems, programmable controllers, analog recorders, dedicated control systems, and any other applications where monitoring of temperature, pressure, flow and analog signals are required. Since each input module features two simultaneous outputs, the voltage output can be used to provide an input to a microprocessor-based data acquisition or control system while the current output can be use for analog transmission, operator interface, or an analog backup system.
