For building a complete or similar system, the following related Honeywell Experion Series-C modules are recommended:
CC-PUIO31: A universal I/O module often used alongside the SPM for additional process inputs and outputs in an Experion PKS system.
CC-PWR401 / CC-PWRB01 / CC-PWRR01: Power supply modules for the Series-C system, providing the necessary 24 VDC power to the I/O rack and modules. These are essential for a complete system setup.
8C-PCNT05 C300 Controller Module: The primary controller module for the Experion PKS system that receives the voted speed signal from the CC-PSP401 for overall system regulation and control.
Q1: What is the primary function of the CC-PSP401 module?
It is designed to monitor the rotational speed of critical machinery (like turbines and compressors) and execute a protective shutdown (trip) when it detects unsafe conditions such as overspeed or underspeed.
Q2: What types of speed sensors can be used with this module?
The CC-PSP401 supports both passive magnetic pickups and active 24 VDC sensors. This flexibility allows it to interface with a wide range of existing speed sensing equipment without requiring additional signal conditioners.
Q3: Can the CC-PSP401 be replaced without shutting down the control system?
Yes, the module supports hot-swapping. When installed in a compatible redundant IOTA (I/O Termination Assembly) configuration, it can be replaced while the system is running, which minimizes downtime.
Q4: Is the CC-PSP401 suitable for use in safety-critical applications?
Yes. With its 2oo3 voting architecture, high diagnostic coverage (>99%), and rapid response time, the module is designed and certified to meet the requirements for SIL 3 (Safety Integrity Level 3) safety instrumented functions.
