This device may also have an excitation output.

If the Dual Display model has a Low Voltage power supply option, then excitation is not available.

Excitation is not available if communication option is installed.

Figure 2.12 Excitation Output

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 Figure 2.13.
