DescriptionThe 3B Series Signal Conditioning I/O Subsystem provides a low cost, versatile method of interconnecting real world analog signals to a data acquisition, monitoring or control system. It is designed
The 3B16 is a single-channel signal conditioning module which interfaces, amplifies, and filters signals from 4-arm full-bridge strain-gage bridges with a resistance from 300W to 1kW. The
module provides a constant +10V bridge excitation voltage and provides simultaneous precision voltage and current outputs. The user-configurable Model 3B16-00 can be applied in applications involving large tare weights which must be compensated with zero suppression. The 3B16 protects the computer side from damage due to field-side over-voltage faults up to 130V rms. In addition, the current output withstands 130V rms without damage and interfaces user equipment through screw terminals located on the 3B Series backplane. The 3B16 is a plug-in, mix-and-match, hot-swappable module which is easily field calibrated via front-panel zero and span adjustments for both voltage and current outputs.
3B Series Custom-Ranging Program Externallyprogrammable Model 3B16-00, enables the user to configure a special input range, including tare weight suppression, by using the optional plug-on AC1310 ranging card, which houses usersupplied resistors to determine zero and span. To facilitate selecting resistors, a Windows program, 3B-CUSTOM, calculates resistor values based on the user-desired input/output ranges.
A chopper-stabilized low-drift (+1uV/oC) input amplifier assures long-term stability. At the amplifier input, a stable, zeroscale input voltage is subtracted from the input signal to set the zero-scale value. Zero suppression can exceed 100% of the input range. This is ideal for expanded-scale applications requiring high-resolution measurement of a selected portion of an input signal. For user convenience, the zero and span can be factory configured to meet custom range needs (Model 3B16- CUSTOM) or can be externally programmed (Model 3B16-00)
via user supplied resistors inserted in the optional AC1310 plugon ranging card. Internal low-pass filtering with a 3 Hz cutoff (-3dB) two-pole Butterworth filter enhances a 60 dB normalmode rejection at 50/60 Hz, enabling accurate measurement of small signals in high electrical noise.
