Operating Function
The Keyphasor signal identifies a reference position on a rotating shaft. The module processes incoming pulses and supplies timing references to compatible monitoring modules. These references help the 3500 system calculate shaft speed and phase-related parameters.
The module supports two input channels. The overall number of Keyphasor signals depends on the rack configuration and the number of installed modules.
Replacement Considerations
Before replacing the 125792-01, check the installed module, I/O configuration, termination arrangement, and required signal-processing functions. Do not assume that another module is compatible based on its model number alone.
Frequently Asked Questions
