Note on Configuration: The 176449-02 is the front card of the 3500/42M monitor. It requires a compatible I/O module (rear card) and a terminal base to complete the assembly and connect field wiring.
| Model | Description | Typical Application |
|---|---|---|
| 3500/42M-01-00 | Complete monitor kit (includes 176449-02 front card + I/O module) | Standard 4-channel vibration/position monitoring |
| 176449-01 | I/O module (rear card) for 3500/40M/42M series | Field wiring termination and signal conditioning |
| 3500/40M | Dedicated Proximitor Monitor (radial vibration/position) | Where seismic inputs are not required |
| 3500/22M | Transient Data Interface (TDI) | System 1 data collection and diagnostics |
| 3500/15 | Power Supply Module | Required to power the 3500 rack |
| 3300 XL Probes | 8mm proximity probes (e.g., 330101, 330103) | Primary displacement sensors for the 42M |
Q1: What is the primary function of the 176449-02?
It is the front card of the 3500/42M monitor. It processes signals from proximity probes and seismic transducers, continuously comparing input values against user-programmable alarm setpoints to protect rotating machinery.
Q2: How many channels does this module support?
The 3500/42M supports 4 independent channels, each of which can be individually configured for different measurement types (displacement, velocity, or acceleration).
Q3: What is the difference between the 3500/42M and the 3500/40M?
The 42M is the more versatile "Multimode" version, accepting both Proximitor and Seismic inputs. The 40M is typically specialized for Proximitor (displacement) inputs only.
Q4: What does the "M" in 3500/42M signify?
The "M" designation indicates enhanced "Multimode" capability, allowing each channel pair to be independently configured for different measurement types and offering faster data sampling than the standard 3500/42.
Q5: Is the 176449-02 still available?
It is an active/mature product within the 3500 series. Availability depends on stock from authorized distributors and the aftermarket. The 3500 platform remains widely supported, though Bently Nevada continues to develop the next-generation Orbit 60 platform.
