Main Features and Advantages
Dual-Channel Precision Monitoring: The BENTLY 128277-01 supports simultaneous analysis of two vibration channels, enabling comprehensive assessment of shaft dynamics of machinery. This capability allows early detection of imbalances, misalignments, or bearing wear, reducing the risk of unexpected failures in critical equipment.
Adaptive Signal Processing: With configurable filter settings (low-pass, band-pass) and alarm thresholds, the module adapts to unique machinery profiles. Engineers can tailor parameters via BENTLY’s software to prioritize specific frequency ranges or vibration severity levels, enhancing diagnostic accuracy for applications like turbine blade monitoring or compressor shaft analysis.
Rugged Industrial Design: Encased in an IP23-rated stainless-steel housing, the BENTLY 128277-01 withstands harsh conditions, including dust, moisture, and electromagnetic interference (EMI). Its wide temperature range (-25°C to +60°C) makes it suitable for offshore platforms, power plants, and manufacturing floors with extreme environmental demands.
Seamless System Integration: As part of the 3500 Series, the module connects directly to BENTLY’s 3500/22M vibration monitors and 3500/92 communication gateways, forming a unified protection system. This integration eliminates compatibility issues and streamlines data aggregation for centralized machinery health management.
Real-Time Diagnostics: Built-in self-test functions and front-panel LED indicators provide instant status updates, while diagnostic logs track historical performance trends. This proactive approach reduces mean time to repair (MTTR) by identifying potential issues before they escalate.

Installation and Maintenance
Pre-installation Preparation:
Before installing the BENTLY 128277-01, verify the following:
Before installing the BENTLY 128277-01, verify the following:
- Ensure the control rack is grounded to prevent electrostatic discharge (ESD) and the power supply matches 24 VDC ±10%. Use BENTLY’s configuration software to define input types (proximity probe or accelerometer) and set initial alarm thresholds based on machinery specifications.
- Mount the module in a 19″ rack with 50 mm clearance for airflow, avoiding adjacent high-heat components. Route sensor cables separately from high-voltage wiring to minimize EMI interference.
Maintenance Recommendations:
- Routine Inspections: Monthly visual checks of front-panel LEDs (green for normal, red for faults) and cleaning dust from ventilation slots. Annually calibrate input channels using a BENTLY 3300 System Calibrator to maintain measurement accuracy.
- Firmware Management: Periodically update firmware via BENTLY’s software to access new diagnostic features and compatibility with emerging industry standards.
- Environmental Monitoring: Regularly assess ambient conditions to ensure temperature (-25°C to +60°C) and humidity (5–95%) remain within limits, replacing seals or ventilation filters as needed.
