7.4 Function Features, Working Principle, Application, Installation & Precautions
- Multi-type sensor signal compatible processing, integrating power supply output for eddy current preamplifiers and passive velocity sensor signal conditioning
- Configurable multi-stage low-pass signal filtering, filtering out high-frequency electromagnetic noise interference to improve measurement signal stability
- Built-in programmable vibration amplitude threshold logic; when input vibration signal exceeds set threshold, relay contact outputs trip signal to drive equipment emergency shutdown protection logic
- Standard rack plug-in hot-swappable design, convenient on-site module replacement without powering off the entire monitoring cabinet
