3500/25-01-00-00 125800-01 Main functions:
Receive input signals from eddy current sensors or electromagnetic sensors
Convert the signal into a digital key phase signal
Indicates when the keyphase marker on the shaft is below the keyphase sensing probe
The 3500 monitoring system can receive up to four key signals, each of which is a digital synchronous signal pulse, used for monitoring modules and external diagnostic equipment to measure vector parameters such as 1X octave amplitude and phase
3500/25-01-00-00 125800-01 Technical features:
Improved Keyphasor Module Provides Enhanced Keyphasor Signal Processing Capabilities
Maintain downward compatibility with existing Keyphasor modules, which can be used in legacy systems
In Triple Modular Redundancy (TMR) applications, modules work in parallel to provide primary and secondary keyphasor signals
Pairing configuration allows the system to accept up to eight keyphasor signals
3500/25-01-00-00 125800-01 Application environment:
Suitable for industrial control applications of various scales, especially in applications that require precise monitoring of shaft speed and phase
3500/25-01-00-00 149369-01 Specifications:
Power consumption: 3.2 watts under normal conditions
Input signal range: -0.8V to -21.0V for non insulated I/O modules,+5V to -11V for insulated I/O modules
Input impedance: less than 21.8k Ω
Automatic threshold value: Trigger small signal amplitude of 2V peak to peak, minimum frequency of 120 rpm (2Hz)
3500/25-01-00-00 125800-01 Configuration and Compatibility:
In TMR applications, it is recommended to use two keyphasor modules
Pairing configuration requires two consecutive monitoring positions on top/bottom or two and a half slot positions
The four key phasor modules will accept four main and four backup input channels, and provide four output channels (one for each module)
