Recommended surge suppression: For relay contact outputs, refer to the SLC 500 Modular Hardware User Manual, publication

1747-UM011

. Connecting surge suppressors across your external inductive load will extend the life of SLC 500 relay contacts.

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.
