The four newest out of 30+ Platinum Plus controllers on a site have these installed between the relay card and ribbon cable. However, my understanding is this part is no longer listed for the Platinum Plus controllers.

They have part number 'C-PP-RSF' and 'Relay Spark Filter' is printed on the back side. Anyone know what they are/were intended to do?

Hello,

This small board works as a jumper between the relay board and its corresponding switch card.  The varistors on this board keep any surge from relays that might damage the switch card or anything else in-line.
Hence the name "Relay Spark Filter"

The part number for this board is :

78CPPRSF

Thank you -
