The DynamicSignals/Kinetic Systems V246-BCB2 is an 8-channel bridge signal conditioner designed for VXIbus data acquisition systems. This C-size module delivers complete signal conditioning for bridge transducers, combining bridge completion, programmable excitation, anti-aliasing filtering, and gain control in a single front-end stage. It interfaces directly with VXIbus ADC subsystems and supports the KineticSystems MUX-bus™ architecture.
## Technical Specifications
**Module Architecture**
• Single-width C-size VXIbus module
• Register-based, fully programmable control
• 10-wire transducer hookups
• Optional simultaneous sampling across all channels
**Bridge Conditioning**
• 8 independent channels supporting 1/4-, 1/2-, and full-bridge configurations
• Bridge completion resistors: precision Vishay metal-foil, 120 Ω or 350 Ω (matched pairs)
• Programmable ±shunt calibration per channel with customer-supplied termination resistors
• Programmable excitation voltage and current monitoring
**Filtering**
• 6-pole low-pass filters with Bessel or Chebyshev response
• Cutoff frequencies: 20 Hz, 200 Hz, 1000 Hz, or 2000 Hz (user-selectable)
• Bypass mode with -3 dB point at 20 kHz
**Signal Performance**
• Common-mode rejection ratio: typically better than -110 dB (DC to 120 Hz)
• Optional trifilar-wound inputs for RF rejection to 100 MHz
**Auxiliary Options**
• RTD measurement support (3- or 4-wire configurations)
## Key Features
• Matched precision resistor pairs eliminate bridge balance errors
• Independent programmable excitation enables multi-transducer flexibility
• Selectable filter response adapts to application bandwidth requirements
• Superior CMRR rejects 50/60 Hz line interference and facility noise
• Trifilar input option suppresses high-frequency coupling and RF interference
## Typical Applications
• Automotive body and safety testing (structural load, crash, airbag)
• Rocket engine testing and propulsion diagnostics
• Wind tunnel data acquisition
• General-purpose strain gauge and bridge measurements
• Temperature measurement via RTD transducers
## Compatibility & Integration
Full integration with KineticSystems VXIbus ecosystem. Operates as a front-end signal conditioner for V207 and V208 ADC modules. MUX-bus™ intermodule connectivity for coordinated multi-channel operations.
