3B32

Isolated, Process Current Input 3B32 FEATURES Interfaces, amplifies, & filters a process-current input. Process-current input signals are measured by reading the voltage across an external precision 100Ω resistor (supplied with module). Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 220v rms at the input screwterminals. All 3B32 series modules are mix-and-match and Hot Swappable. FUNCTIONAL BLOCK DIAGRAM Figure 1. 3B32 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 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 for analog transmi...
