Bently Nevada 3500/25 149369-01 Enhanced Keyphasor Module
Bently Nevada 3500/25 149369-01 | Enhanced Keyphasor Module for 3500 Machinery Protection System. Half-height, two-channel module converts proximity probe or magnetic pickup signals into digital Keyphasor outputs. Provides precise timing for shaft speed, phase, and vector measurements. Direct plug-in replacement for 125792-01.
Key Features
2-channel half-height module. Input range 1 to 1,200,000 cpm (0.017 to 20 kHz). Output range 1 to 99,999 cpm. Auto or manual threshold triggering. Buffered Keyphasor outputs at front and rear. -24 Vdc transducer power supply. 3.2W typical power consumption. Main module weight 0.34 kg (0.76 lbs). Supports up to four Keyphasor signals standard, eight in paired configuration. Field-upgradeable firmware.

Ordering Code Breakdown
3500/25-AA-BB-CC
A: Number of Channels – 01 = Single half-height 2-channel card; 02 = Two half-height 2-channel cards (4 channels).
B: I/O Module Type – 01 = Internal Terminations; 02 = External Terminations; 03 = Internal Barrier I/O; 04 = Isolated Internal (Magnetic Pickups); 05 = Isolated External (Magnetic Pickups).
C: Agency Approval – 00 = Not required; 01 = cNRTLus (Class I Div 2); 02 = ATEX/IECEx/CSA (Class I Zone 2).
Installation Notes
Install in half-height front slot using mounting adapter. I/O module occupies corresponding full-height rear slot. Configure trigger threshold (auto or manual) and hysteresis per application. For magnetic pickups, use Isolated I/O modules (B:04 or B:05). For hazardous area installation, follow appropriate control drawings (149243/149244 or 138547).
Engineering Advantages
Supports up to eight Keyphasor signals in paired configuration for complex machinery monitoring. Expanded frequency range handles multi-event-per-turn inputs up to 20 kHz. Auto and manual threshold options accommodate various transducer types. Direct replacement for legacy 125792-01 modules. Buffered outputs at front and rear simplify external diagnostics. Field-upgradeable firmware protects investment.
FAQs
Q1: What is the maximum input frequency?
A1: 20 kHz (1,200,000 cpm), supporting multiple events per revolution.
Q2: What is the difference between Isolated and Non-isolated I/O modules?
A2: Isolated modules (B:04/05) are designed for magnetic pickups and provide isolation from other systems. Non-isolated modules (B:01/02) are for standard proximity probe applications.
Q3: Can this module replace older Keyphasor modules?
A3: Yes, the 149369-01 Enhanced Keyphasor Module is a direct plug-in replacement for Keyphasor Module 125792-01.
