As highlighted in Table 4.1.4, this connector provides:
• 4 opto-isolated input ports which can be used to reveal any failure condition on external
PIN Name Meaning
1 Ground It is a ground terminal for digital inputs, i.e. for pin 2, 3, 9, 10.
2
Digital input n.1
(SW assignable)
This port can be used to monitor external equipment status. Once a default working
status has been assigned (through the Supervision System) to this input port, any
change is detected as a failure signal.
3
Digital input n.2
(SW assignable)
This port can be used to monitor external equipment status. Once a default working
status has been assigned (through the Supervision System) to this input port, any
change is detected as a failure signal.
4 Disconnected pin No meaning

major alarms
These pins present an open circuit if a major alarm is active on the TPRN sub-rack or
on any module hosted in it.

These pins are terminals of an output port (output relay 1), which can be driven
through the Supervision System. The output port can be set to “open” or “close”
condition. These 2 statuses can be used to pilot any external device connected to
subD-15 connector.
