Key Features

• Elite Signal Resolution: Employs 24-bit Sigma-Delta A/D conversion, providing a massive 110 dB SNR. This allows the module to distinguish tiny vibration signatures from background electrical noise, essential for early bearing fault detection.

• Extended Dynamic Range: With a frequency bandwidth spanning from 0.0625 Hz to 40 kHz, it is capable of monitoring everything from slow-speed structural sway to high-frequency gear mesh and aerodynamic instabilities.

• Real-Time Protection Logic: Processes vibration data instantaneously to generate setpoint-based alarms and hardware-level protection states, ensuring machinery is tripped before damage occurs.

• Integrated Condition Monitoring: Fully compatible with System 1™ software, enabling long-term trending, spectrum analysis, and diagnostic reporting for proactive maintenance.

• Flexible Input Architecture: Can simultaneously process multiple sensor types, including accelerometers, velocity transducers, and proximity probes, across its 12-channel dynamic signal capacity.

• Industrial Hardening: Designed for reliable operation in extreme environments, maintaining precision performance across a broad temperature range of -20°C to +65°C.
