3B30

Isolated Voltage Input 3B30 / 3B31 FEATURES Interfaces, amplifies, & filtersanalog input voltages. Narrow-bandwidth (3Hz) single-channel single conditioning. Module provides simultaneous precision voltage and current outputs. Module circuitry can withstand 220v rms at the input screwterminals Current output withstands 130V rms without damage. All 3B30 & 3B31 series modules are mix-and-match and Hot Swappable Figure 1. 3B30 & 3B31 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 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 transmission, operator i...
