ge fanuc card

[PLC_NEWBIE]

does anyone know the different between these two cards?

IC693MDL646

IC693MDL646C

 

[magicsmoke]

They are the same just different revision

This may mean "conformal coating". This is how Modicon/SquareD et al identifies conformal coating. GE may do the same.

In GE Fanuc part numbers, the last alpha character is the revision level. If you order an IC693MDL646 from your distributor, you will get whatever revision level they have available.

Occasionally, there are issues with an old revision level of a module not being compatible with a newer revision level of CPU. GE Fanuc publishes (at tleast tey used to) a compatibility chart that covers those details. In the specific case listed, there are unlikely to be any compatibility issues since the moduel in question is a simple DC input card with a fast filter time.

thanks for the info.........sounds like a revision/firmware disaster like ab

 

[Steve Bailey]

I wouldn't call it a disaster. The cases where there are issues are relatively rare. Where they occur, they are generally in "smart" modules like network interfaces. I'm not aware of any compatibility issues with discrete I/O modules.

A revision letter hear could simply mean that GE Fanuc is getting a component from a different vendor.
