Hello everyone,

I need informations regarding the Siprotec 5 family, I'm wondering in which IO can I find the Coil inputs for Trip relay supervision in the  7SJ85 overcurrent relay for example.

After some researches I found that not all mounting IO can be used for the trip circuit supervision, for that purpose I need 2 contacts in the binary input. Actually in the IO202 all the binary inputs are with 2 contacts so it can be used for the trip circuit supervision.

Please confirm my supposition,if what I said is correct I'm asking if the binary inputs in the IO202 are all able  to be configured to supervise the trip circuit in DIGSI 5 software.

Thank you,
