Recommended surge suppression: For relay contact outputs, refer to the SLC 500 Modular Hardware User Manual, publication
. Connecting surge suppressors across your external inductive load will extend the life of SLC 500 relay contacts.

The continuous current per module must be limited so the module power does not exceed 1440V A.

For DC voltage applications, the make/break ampere rating for relay contacts can be determined by dividing 28V A by the applied DC
voltage. For example, 28V A/48V DC = 0.58 A. For DC voltage applications less than 14V, the make/break ratings for relay contacts cannot
exceed 2 A.
