Description
Bently Nevada 3500/25-01-03-02 Enhanced Keyphasor Module
The 3500/25-01-03-02 Enhanced Keyphasor Module provides precise reference signals for speed and phase measurement in turbomachinery. It delivers reliable Keyphasor pulses to the monitoring system, enabling accurate synchronous sampling and diagnostics for gas turbines, steam turbines, and compressors. This module is ATEX/IECEx certified for hazardous area installations.
Ordering Code Configuration
The 3500/25-01-03-02 part number follows this structure: 3500/25-AA-BB-CC
- AA – Channel Configuration: 01 = Single half-height 2-channel Keyphasor card (option for 2 channels)
- BB – I/O Module Type: 03 = Internal Barrier I/O with Internal Terminations
- CC – Agency Approval: 02 = ATEX/IECEx/CSA (Class 1 Zone 2)

Installation & Field Application Guide
- Install the Keyphasor module in any half-height front slot of the 3500 rack. The I/O module occupies the corresponding rear slot.
- For Internal Barrier I/O, observe the reduced operating temperature range of 0°C to +65°C. Ensure adequate cabinet cooling.
- Use shielded twisted-pair cables for Keyphasor signal wiring. Maintain a minimum bend radius of 10x cable diameter.
- In hazardous area installations (ATEX/IECEx), ensure proper cable glands and sealing per local certification requirements.
Why Choose the 3500/25-01-03-02
- Provides precise Keyphasor pulses for accurate speed and phase measurement.
- Internal Barrier I/O eliminates the need for external safety barriers in hazardous areas.
- ATEX/IECEx/CSA certification allows installation in Class 1 Zone 2 environments.
- Compact half-height design saves rack space while delivering 2-channel capability.
Field Engineer FAQs
Q1: What is the difference between standard I/O and Internal Barrier I/O?
A1: Internal Barrier I/O includes built-in galvanic isolation and zener barriers for hazardous area installations. This eliminates the need for external safety barriers but reduces the operating temperature range to 0°C to +65°C.
Q2: How many Keyphasor channels does this module provide?
A2: The 3500/25-01-03-02 provides 2 Keyphasor channels on a single half-height card. Each channel accepts a proximity probe or magnetic pickup input.
Q3: What is the recommended sensor type for Keyphasor input?
A3: Bently Nevada recommends 3300 XL 8mm proximity probes or magnetic pickups with a voltage output between -0.8V and -21V DC. Ensure the sensor is properly gapped per the installation manual.
