Binary inputs
The dry input circuits, despite being galvanically isolated, must preferably be supplied with the same
auxiliary voltage of the control panel.
The inputs are polarity free with wide voltage range.
The optocupled inputs are immune to transitory interferences, however the following recommenda-
tion must be considered in high disturbed environments:
• Position input wiring away from high energy sources.
• Use shielded cables with ground connection on only one end (preferably at the relay side.
Output relays
Four output relays are available (SPDT, type C):
• K1, K2 and K4 (trip relays).
• K3 (signalling relay).
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..).
All contacts are shown in de-energized state for standard reference
RS232 port
The link from PC and NA10 serial port must be established by means a L10041 cable.
When no RS232 port is available on Personal Computer, a suitable USB to RS232 converter must be
employed.
After installation, the same communication port must be selected to define the ThyVisor parameters
(typically COM4, COM5,...).
