Common FAQ

Can the CP471-50 replace an existing CP461 module?Yes, a pair of CP461 modules can be online-replaced with a pair of CP471-50 modules, provided your system is running CENTUM VP R6.05 or later and uses an EC401 bus coupler with style code S3 or higher. Note that mixing one CP461 and one CP471-50 in a single redundant pair is prohibited.

What is the difference between the -50 and -51 versions?The CP471-50 is the basic standard type, while the -51 version typically includes the ISA Standard G3 option, which adds an extra layer of conformal coating to protect the internal circuitry against corrosive gases
