Technical Specifications Multi‑channel vibration sensor input interfaces, internal logic bus interface, auxiliary DC power supply input. Operating temperature 0 ℃ to +60 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Circuit board surface conformal coating provides environmental protection.
Functional Features Conditions raw vibration signals from accelerometers and velocity sensors. Implements analog filtering for industrial site noise suppression. Converts analog vibration signal into digital data for system processing. Supports channel fault detection for sensor open‑circuit and short‑circuit. Outputs vibration amplitude and frequency related characteristic data.
Application Scenarios Spare vibration monitoring board for rotating machinery protection system. Applied in turbine, fan, pump and motor condition monitoring in power, petrochemical and metallurgy industries.
Performance Parameters High‑precision analog signal conditioning capability. Stable vibration signal sampling performance. Reliable sensor channel fault detection function.
Material Composition Multilayer glass‑fiber epoxy printed circuit board. Vibration signal conditioning circuit, analog‑to‑digital conversion chip, logic processing assemblies. Multi‑pin plug‑in connectors and metal screw mounting hardware. Conformal protective coating layer.
Structural Characteristics Rectangular circuit‑board structure. Sensor input connectors and system bus connectors are distributed on different board edges. Reserved screw mounting holes for cabinet internal fixation. Analog signal area and digital logic area are separated on PCB layout.
Working Principle TVB3101‑1ISC obtains auxiliary DC working power. Vibration sensor analog signals enter input channels, pass through amplification and filtering circuit. The board converts analog vibration signals into digital values, then transmits digital vibration characteristic data to system main controller via internal bus.
Installation Requirements Fasten board to cabinet mounting bracket with mounting screws. Fully insert and lock each plug‑in connector. Restore auxiliary power supply, configure sensor parameters in engineering software, verify vibration measuring data consistency with field actual equipment status.
Usage Notes Sensor wiring shall follow shielding grounding specification.
