This device has snubber circuits designed to protect the contacts of the

mechanical relays when it switches inductive loads (i.e. solenoids, relays). These snubbers are internally connected between the Common (C) and Normally Open (NO) relay contacts of Output 1 and Output 2.

If you have an inductive load connected between Common (C) and Normally Closed (NC) contacts of the mechanical relays and you want to protect them from the rush current during the switching period, you have to connect an external snubber circuit between Common

(C)and Normally Closed (NC) contacts as indicated in the figure below.
