Description
BENTLY 135473-01 Product Specification
1. Product DescriptionThe
BENTLY 135473-01 is a
Keyphasor I/O Module designed for the
3500 Machinery Protection System, providing isolated signal conditioning for hazardous environments. It integrates internal barriers and terminations, eliminating external safety components. The module supports magnetic pickup and Proximitor sensor inputs, enabling precise shaft speed measurement and phase reference for machinery such as turbines and compressors. While primarily optimized for speed monitoring, it also offers phase measurement with minimal latency. Its compact design and compliance with CE/RoHS standards ensure reliability in harsh industrial settings.

3. Advantages and Features
- Isolation: Protects against ground loops and voltage spikes in parallel signal applications.
- Dual Functionality: Supports both speed measurement (primary) and phase monitoring (secondary).
- Hazardous Area Compliance: CE, RoHS, and SIL 2 certifications for use in explosive zones.
- Flexible Inputs: Compatible with magnetic pickups and Proximitor sensors (with external power).
- Real-Time Monitoring: Generates alarms based on user-defined thresholds.
4. Application Fields
- Industries: Oil & gas, petrochemical, power generation, and manufacturing.
- Typical Use Cases:
- Shaft speed and vector vibration analysis (e.g., 1X amplitude/phase).
- Phase reference for machinery alignment and balancing.
5. Competitor Comparison
Compared to generic isolated I/O modules, the 135473-01 offers tighter integration with BENTLY’s 3500 system and Proximitor sensors. Its advanced signal conditioning minimizes phase distortion, outperforming alternatives in high-precision applications.
6. Selection Recommendations
- Compatibility: Ensure alignment with 3500 rack configurations (e.g., 3500/15 controller).
- Environment: Verify temperature and IP ratings match site conditions.
- Phase Requirements: Opt for non-isolated modules if minimal phase shift is critical.
7. Precautions
- Installation: Power off the 3500 system before module replacement.
- Sensors: Use BENTLY-approved sensors for hazardous areas.
- Firmware: Regularly update firmware for optimal performance.
