3500/42M Adaptation Module (4-Channel Proximitor/Seismic)
The 3500/42M Adaptation Module is a 4-channel eddy current and seismic monitoring interface module used in conjunction with the 3500/42M front monitor (Front Card 176449-02). It provides signal adaptation, isolation, and intrinsic safety functions for machinery condition monitoring applications.
Channel Configuration and Sensor Support
4 independent measurement channels
Supports eddy current proximity probes (e.g. 3300 XL) and seismic sensors (acceleration or velocity)
Each channel is equipped with an integrated safety barrier, providing electrical isolation and energy limitation
Intrinsic Safety and Hazardous Area Compliance
The integrated safety barrier limits current and voltage levels in accordance with ATEX and IECEx intrinsic safety requirements, preventing excessive energy transfer into hazardous areas and ensuring protection of personnel and field equipment.
Signal Interfaces and Transmission
Input interface: Euro-style 12-pin connector, compatible with sensor cables and preamplifiers
Signal output: Buffered sensor signal supporting 4–20 mA and 0–10 V interfaces
Fully compatible with PLC/DCS systems and external data acquisition equipment
Power Supply
Power is shared between the 3500 rack backplane and the 3500/42M front module
Supply voltage range: 18–30 VDC
Functional Features
Integrated safety barrier
Each channel includes a built-in safety barrier that limits energy transmission during fault conditions, supporting safe operation in hazardous environments.
Signal isolation
Electrical isolation between the four channels minimizes inter-channel interference, improving measurement accuracy and long-term signal stability.
Simplified wiring
The internal terminal and connector design simplifies sensor wiring, reduces installation time, and minimizes the risk of on-site wiring errors.
System Integration and Applications
The adaptation module integrates seamlessly with the Bently Nevada 3500 system and System 1 software, supporting:
Paired-channel configuration
Alarm and protection parameter setup
Condition monitoring and diagnostics
It is well suited for critical rotating machinery applications, including steam turbines, gas turbines, compressors, and other high-value assets.
