简 介:Isolated AC Sine Wave Input 3B42 / 3B43 / 3B44
FEATURES
AC averaging technique used to rectify, amplify, and filter 50 Hz to 400 Hz sine-wave signals. Accepts inputs of between 20 mV to 550 V rms to give an rms output reading. Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 130v rms at the input screwterminals. All 3B42, 3B43, & 3B44 series modules are mix-and-match and Hot Swappable.

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 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 used ……
