This device may also have an excitation output.
Figure 2.12 Excitation Output
Excitation is not available if communication option is installed.
This device has snubber circuits designed to protect the contacts of the
mechanical relays when it switches to 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.
