The YOKOGAWA CP461-50 is a processor module for Yokogawa Field Control Units used in CENTUM VP process control systems. It is designed for AFV300/AFV400-class Field Control Units and can operate in a dual-redundant configuration using two identical CP461 modules. The CP461-50 is the standard type without explosion protection and is identified as a replacement for the earlier CP461-10. Yokogawa documentation also identifies CP461 as a processor option for compatible Field Control Units and specifies that dual-redundant configurations require two identical processor modules.

FAQ
Q: What is the CP461-50 used for?
A: It functions as the processor module of a compatible Yokogawa Field Control Unit, executing control processing and coordinating system I/O.
Q: Can two CP461-50 modules be used together?
A: Yes. Yokogawa documentation specifies that two identical CP461 modules can be installed for a dual-redundant configuration.
Q: What does the “-50” suffix mean?
A: The “-5” identifies the standard type without explosion protection, while “0” identifies the basic type.
Q: Is CP461-50 compatible with CP471?
A: CP461 and CP471 have specific replacement and configuration requirements. Yokogawa documentation states that CP471 cannot coexist with CP461 in the same dual-redundant pair, and replacement from CP461 to CP471 requires authorized service-engineer procedures.
Q: What should be checked before replacement?
A: Verify the complete model code, Field Control Unit type, software version, redundancy configuration, and existing processor revision before installation.
