Key Features and Engineering Advantages
Cybersecurity Isolation:The "Secure" designation refers to the module's ability to pull diagnostic data without interfering with the underlying protection rack, preventing external network issues from compromising the machinery trip logic.
High-Density Parallel Sampling:Unlike multiplexed systems, the 2155/40-02 samples all24 dynamic channels simultaneously, ensuring that phase relationships between different vibration points are perfectly preserved for accurate orbit and waveform analysis.
Dual Ethernet Redundancy:Features two RJ45 ports to support redundant network architectures, ensuring that condition monitoring data remains available even if one network path fails.
Unified Data Acquisition:Combines dynamic vibration signals with process inputs (like temperature and pressure), providing a holistic view of machinery health within a single diagnostic environment.
Condition Monitoring Foundation:Designed specifically to feed theSystem 1®platform, allowing for automated rule-based alerts and long-term trend analysis of critical equipment.
