The 3500/40-01-CN is a high-performance, four-channel Proximitor Monitor module for the Bently Nevada 3500 Series Machinery Protection System. This module is designed to accept signals from Bently Nevada proximity transducers, processing them to provide continuous monitoring of critical machinery parameters such as radial vibration, axial thrust position, eccentricity, and differential expansion.
The primary function of the 3500/40 is to compare these processed signals against user-defined alarm setpoints to drive machinery protection alarms. The "CN" designation indicates that the module and its associated I/O are certified for use in hazardous areas specifically under Chinese regional regulatory standards.
The module configuration defines the interface and regulatory compliance:
Four-Channel Monitoring: A single module monitors up to four individual transducer inputs, maximizing rack density.
I/O Module Type (01): Includes the Proximitor I/O Module with Internal Terminations. This version allows field wiring to be connected directly to the I/O module in the back of the 3500 rack, eliminating the need for external terminal blocks or specialized cables in standard installations.
Data Integration: Provides conditioned signals to the 3500 backplane for use by relay modules, the Communication Gateway, and the Rack Interface Module (RIM) for transient data collection.
Agency Approval (CN): Specifically certified for the China market (NEPSI/CCC), ensuring compliance with local safety and explosive atmosphere requirements.

Can I monitor both Vibration and Thrust on the same 3500/40 module?
Yes. Each of the four channels is independently programmable. You can configure Channel 1 for Radial Vibration and Channel 2 for Thrust Position using the 3500 Rack Configuration Software, provided the correct transducer types are connected.
What is the difference between Internal and External Terminations?
Option 01 (Internal) means you wire the sensors directly to the green terminal blocks on the I/O module. External terminations (Option 02) would require a separate External Termination Block and an interface cable, which is typically used for high-density wiring or when sensors are pre-wired to a specific panel section.
How do I verify the module is functioning correctly?
The front of the module features status LEDs:
OK: Solid green indicates the module is hardware-healthy.
TX/RX: Flashing indicates active communication with the Rack Interface Module.
TM: Indicates the module is in "Trip Multiply" mode.
Bypass: Indicates one or more channels are bypassed for maintenance.
Slot Placement: The 3500/40 can be placed in any of the rack slots from 2 to 15. Slot 1 is reserved for the Rack Interface Module (RIM).
Configuration: You must use the 3500 Rack Configuration Software to set the transducer scale factor (e.g., 200 mV/mil for 8mm probes) and the specific alarm setpoints (Alert and Danger).
Hot-Swapping: The 3500/40 is designed for "hot-swapping," meaning you can replace the main module while the rack is powered. However, ensure the "Rack Key Lock" is in the proper position to allow configuration changes and be aware that machinery protection for those four channels will be lost during the swap.
Wiring Integrity: When using internal terminations, ensure the shield wire of the transducer cable is correctly landed on the "SHLD" terminal to prevent electromagnetic interference (EMI) from inducing false vibration readings.
