• Output Signals: TTL-level Keyphasor pulse, buffered sensor output, and relay outputs for alarms
• Sampling and Processing: Synchronized with the 3500 rack timing for phase-coherent data acquisition
• Power Supply: Powered by the 3500 rack backplane (24 V DC nominal)
• Operating Temperature: 0°C to +60°C
• Storage Temperature: -40°C to +85°C
• Humidity Range: 5% to 95% relative humidity, non-condensing
• Certifications: CE, ATEX (for applicable hazardous area configurations), FM, CSA, IECEx
• Communication: Interfaces with 3500 rack communication cards (e.g., 3500/32, 3500/92) for data transmission to monitoring systems

Functional Features:

• Keyphasor Signal Generation: Produces a once-per-revolution timing pulse used for phase measurement in vibration analysis
• Rotational Speed Measurement: Calculates RPM from sensor input for real-time speed monitoring
• Dual-Channel Redundancy: Supports dual sensor inputs for redundancy and improved reliability
• Signal Buffering: Provides isolated outputs for connection to oscilloscopes, PLCs, or DCS systems
• Diagnostics: Continuous self-monitoring and fault detection with status reporting to the 3500 rack
• Configurable Settings: Adjustable parameters such as trigger level, filter settings, and pulse width via software (e.g., System 1 or AMS Machinery Health Manager)
• Integration with Protection System: Works in conjunction with other 3500 modules (e.g., 3500/42M, 3500/44) for comprehensive machinery protection

Applications:

• Turbines: Steam, gas, and hydro turbines in power generation facilities
• Compressors: Centrifugal and reciprocating compressors in oil & gas, petrochemical, and process industries
• Pumps and Motors: Large rotating equipment in industrial plants requiring condition monitoring
• Fans and Blowers: Critical ventilation systems in power stations and manufacturing
• Marine Propulsion Systems: Monitoring of main engines and auxiliary turbines onboard ships
• Aerospace Test Rigs: Used in ground testing of jet engines and rotating components
