3B45 Datasheet | Analog Devices

FEATURES Interfaces, isolates, & filters frequency inputs. The 3B45 accepts full-scale inputs from 25 to 1100 Hz The 3B46 accepts full-scale inputs from 520 Hz to 25 k Hz. Modules provide simultaneous precision voltage and current outputs. Modules circuitry can withstand 130v rms at the input screwterminals. All 3B45 & 3B46 series modules are mix-and-match and Hot Swappable. Figure 1. 3B45 & 3B46 Functional Block Diagram 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 microputer-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 used for analog transmission, operator interface, or an analog backup system. Each input module is a single-channel signal conditioner which plugs into a socket on the backplane and accepts its signal from the input screw terminals. All input modules provide input protection, amplification and filtering of the input signal, accuracy of +0.1%, low drift of +1 u V/ o C (low-level input modules), and feature two high-level analog outputs that are patible with most process instrumentation. The isolated input modules also provide +1500 V peak isolation. The choice of a specific...
