Honeywell Speed Protection Module

CC-PSP401 · Series C Turbomachinery Protection

A multifunction Series C module for qualified speed measurement and local protection action.

Technical Summary

CC-PSP401 conditions turbine speed signals, evaluates protection limits and coordinates local trip action with the Series C control environment. Its supporting general I/O serves the same turbomachinery protection application.

Replacement

Confirm firmware, control strategy, terminal assignment, probe excitation and trip-relay wiring before replacement. Validate the complete protection loop after installation.

FAQ

Question Answer
Can a general-purpose I/O module replace it? No. Use the approved Speed Protection Module configuration.
Where should trip settings be verified? In the approved project configuration and protection documentation.
What diagnostics require review? Review probe health, wiring status, channel qualification and output feedback.
What is required after installation? Complete the approved functional and overspeed protection tests.
