Product Description

Bently Nevada 3500/25 125792-01 Enhanced 2-Channel Keyphasor Module

Precision Keyphasor Timing & Speed Monitoring for 3500 Machinery Protection Systems

1. Core Overview

The Bently Nevada 3500/25 125792-01 is a half-height, 2-channel Enhanced Keyphasor Module for the 3500 Machinery Protection System, designed to deliver precise shaft timing, speed measurement, and 1X vibration phase reference in power generation, oil & gas, and heavy industrial machinery. It accepts inputs from proximity probes or magnetic pickups, converting them to digital Keyphasor signals for 3500 monitor modules, enabling accurate shaft speed (±0.05% accuracy, 0.1 RPM resolution), vector vibration analysis, and machinery synchronization. With hot-swappable design, galvanic isolation, and real-time diagnostics, it ensures reliable operation in harsh industrial environments, supporting up to 8 Keyphasor inputs in paired configurations for TMR redundancy.

• Core Role: 2-channel Keyphasor for 3500 MPS; shaft speed measurement, 1X vibration phase reference, timing sync • Model Info: 3500/25 (PN: 125792-01); Bently Nevada (GE Digital); Enhanced Keyphasor Module • Key Specs: 2 channels; ±0.05% speed accuracy; 0.1 RPM resolution; -40°C to +85°C; 3.2W power • Reliability: Hot-swappable; galvanic isolation; LED status; IEC 61010 safety compliant

2. Input/Output & Signal Performance

The module features 2 isolated input channels for proximity probes (8mm/11mm) or magnetic pickups, handling -24Vdc input signals with 1000 Hz sampling rate. It generates digital Keyphasor outputs (once-per-turn/multi-event pulses) and 4-20mA speed signals for DCS/PLC integration, with 2.5kV galvanic isolation between channels and backplane to prevent noise interference. Each channel includes LED indicators for signal presence/fault, and built-in diagnostics support real-time event logging, fault history tracking, and 3500 Rack Configuration Software (RCS) integration for remote troubleshooting.

• Inputs: 2 channels (proximity probe/magnetic pickup); -24Vdc; 1000 Hz sampling rate • Outputs: Digital Keyphasor pulses; 4-20mA speed signal; buffered outputs for 3500 monitor modules • Isolation: Galvanic isolation (channel-channel/backplane); 2.5kV isolation voltage; 10V/m EMI immunity • Diagnostics: LED status (signal/fault); RCS integration; event logging; remote alarm reset

3. 3500 System Integration & Redundancy

The 3500/25 integrates seamlessly with 3500 racks, supporting up to 4 Keyphasor inputs in standard config and 8 in paired mode for TMR redundancy. It uses 3500 backplane for power (24Vdc) and communication, enabling hot-swappable replacement without system shutdown. Integration with 3500/40M, 3500/42M monitor modules enables coordinated vibration phase analysis and speed-based protection logic, while RCS software allows "One-Shot" configuration, I/O mapping, and real-time data monitoring. It also interfaces with DCS/SCADA via Modbus RTU/TCP for remote process control.

• System Compatibility: 3500 racks; 3500/40M/42M monitors; RCS configuration software • Redundancy: TMR-ready; paired module config for primary/secondary Keyphasor signals • Installation: Half-height; hot-swappable; backplane-powered (24Vdc); screw-terminal wiring • Communication: 3500 backplane; Modbus RTU/TCP; DCS/SCADA connectivity; 10/100 Ethernet
