programming.
AUX-IN external modules allow the thresholds setting for the binary inputs activation.
The digital inputs switching threshold can be set during installation so that the command voltage is
comparable to the supply voltage.
The inputs are immune to transitory interferences, however the following recommendation must be
considered in high disturbed environments:
• Position input wiring away from high energy sources.
• Set a debounce timer (tON and/or tOFF) to alloy the transient to decay.
• Use shielded cables with ground connection on only one end (preferably at the relay side.

Ethernet Ports
Pro_NX relays are supplied with two Ethernet ports with TX (RJ45) or FX (fi ber optic) connection, and
ModBus / TCP or IEC 61850 protocol.
The following options are available:
A) TX + FX ports
[1]
B) TX + TX ports
[1]
C) FX + FX ports
[1]
D) FX + FX + RSTP
[2]
Connections to TX ports (RJ45) must be made with shielded cable FTP Cat.5e category or higher.
The link must be enabled by means ThySetter sw and local connection:
• Set the IP address (
Host IP address
and
IP net mask
) n order that the NVA100X and PC parame-
ters are matched.
• Set to OFF parameters
Autonegotiation
on relay.
Parameters are inside the
Communication \ Ethernet
submenu. Dopo aver eseguito le modifiche, af-
finché le nuove impostazioni relative alla comunicazione Ethernet siano attive, è necessario togliere
l’alimentazione ausiliaria e successivamente rialimentare il relè.

Local Port
A cross cable must be used for connection between computer and local port.
Nota 1 The TX (RJ45) and FX (fi bra ottica) Ethernet port are multiplexed (single IP address). Under normal conditions, the primary port is active, while the
secondary port is activated in the event of failure of the primary port or by means of hw-sw switching command.
Note 2 Two simultaneously active Ethernet ports with RSTP protocol
