Features:
- Widening Of Narrow Keyphasor Pulses Ensures Accurate Speed And Phase Detection
- DIN Rail Mounting Provides Flexible And Secure Installation Within Control Cabinets
- Wide Operating Temperature Range With +24V DC Power Supports Industrial Environments
The Bently Nevada 100M1554 Pulse Expander Module is a vital accessory for the 3500 Series, designed to address limitations in detecting extremely narrow keyphasor signals. It is particularly useful in high-speed or small-diameter machinery where brief pulses may cause errors in phase and speed measurement. By extending pulse widths, it ensures reliable signal acquisition, improving system stability and monitoring accuracy.
Its robust design allows it to operate in challenging industrial environments with temperatures ranging from -40 °C to +70 °C and standard +24V DC power. The DIN rail mounting provides flexibility, making it easy to integrate into existing cabinets without disrupting the 3500 system configuration.
By incorporating the Bently Nevada 100M1554 Pulse Expander Module, plants benefit from accurate dynamic monitoring, reduced false alarms, and improved predictive maintenance capabilities. It complements other 3500 Series modules seamlessly, enhancing overall machinery protection and operational reliability.
The 100M1554 Bently Nevada Pulse Expander Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Product Family 100M1561,100M1560,100M1555
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- 3500/25 Module Firmware Compatibility: Ensure the 3500/25 key phase card firmware version supports external trigger adjustment to recognize the broadened signal.
- Rack Configuration Software: The key phase trigger threshold must be set to "External Conditioning" mode in the software.
- Hardware Version Iteration: Early A versions and later improved versions have minor optimizations in power consumption and pulse response time; the serial number must be verified during replacement.
- No Program Update Required: This module typically does not have user-programmable firmware; the logic is implemented by internal ASIC or hard circuitry. Maintenance focuses on checking physical wiring.
- CE Certification: Complies with EU Electromagnetic Compatibility (EMC) Directives.
- CSA/NRTL/C: Complies with North American electrical safety standards, allowing installation in industrial control cabinets.
- Ex/ATEX Intrinsic Safety Certification: Typically requires use with safety barriers; complies with non-increased safety area installation standards.
- ISO 9001: Manufacturing processes adhere to general mechanical protection system quality standards.
- Ultra-high-speed turbines: Speeds exceeding 10,000 RPM result in extremely short scan times of the key phase marker across the probe.
- Small-diameter journal monitoring: The shaft diameter is too small, and the physical groove width is insufficient to generate a sufficiently long electrical pulse.
- Long-distance signal compensation: Prevents narrow pulses from being "smoothed out" due to capacitance effects during long cable transmission.
- Multi-tooth disc speed measurement: In certain turning gear or multi-gear speed measurement applications, converts high-frequency narrow pulses into square waves recognizable by the 3500 system.
