Compatibility and replacement
Order with the complete Panasonic part number FX-551-C2; suffixes such as P (PNP output) or -C2 (2 m cable) change the version, so check the label of the old amplifier.
If the label of the old part is worn or the model is discontinued, send us a photo and we will confirm the current Panasonic equivalent before quoting.
What to check first
- DIN-rail mounting space
- NPN or PNP output
- Cable or connector connection
