Notes
I corresponds to the real state of the contact
connected to the input of the programmable
relay.
i (or I) corresponds to the inverse state of
the contact connected to the input of the
programmable relay.
The coil is energised when the contacts to which
it is connected are closed.
The coil is energised when the contacts to which
it is connected are closed.
It remains tripped when the contacts re-open.
The coil is de-energised when the contacts to
which it is connected are closed.
It remains inactive when the contacts re-open.
