Output relays
Six output relays are available on board.
It is advisable to verify that the technical characteristic of the contacts be suitable for the applied
load (about current, nominal voltage, make and break current , etc..).
Output relay K1 and K2 have one change over contacts (SPDT, type C).
Output relay K3 and K4 have one make contact (SPST-NO, type A) and a common reference (A10
terminal).
Output relay K5 and K6 have one make contact (SPST-NO, type A for K5), one break contact (SPST-
NC, type B for K6) and a common reference (A13 terminal).
All contacts are shown in de-energized state for standard reference.
USB port
The link from PC and NA10 USB port must be established by means a L10042 cable.
After installation, the same communication port must be selected to define the ThyVisor parameters
(typically COM4, COM5,...).
Ethernet port
One RJ45 (copper) or FX (optics fiber) port may be provided.
Connections to the TX (RJ45) port must be made with shielded cable FTP Cat.5e category or higher.
For testing a PC may be directly connect to the Ethernet port (D1) on the rear side.
With TX interface a cross cable must be employed, while an Ethernet-optical fiber converter, suit-
able for 100 Mb data rate must be employed if an FX port is implemented.
The link must be enabled by means ThyVisor sw and USB connection:
• Set the IP address (
Host IP address
e
IP net mask
) in order that the NA10 and PC parameters
are matched; the parameters are inside the
Communication \ Ethernet
submenu.
• Set to
OFF
the
Autonegotiation
parameter of NA10 device (
Autonegotiation
parameter inside
Communication \ Ethernet
submenu).
For security reasons, a change of the Ethernet communication parameters become active only after
an hw reset.
RS485 port
RS485 communication circuit connections must be made using screened twisted pair cable observ-
