NVA100X - Getting started - 01 - 2018
ThySensor inputs
(NVA100X#P)
The inputs current and voltage connections are made through pre-wired L1, L2 and L3 RJ45 plug.
For the A1, A2 and U1, U2 screw terminals with following characteristics are available:
• Nominal cross section:
0.2 to 4 mm
2
(AWG 24...10) for single conductor
0.2 to 1.5 mm
2
for two conductors with same cross section
• Tightening torque:
0.5-0.6 Nm
• Stripping length:
7 mm
For the IN1C-1...16, IN2D-1...16, OC1E-1...16 and OC2F-1...16 connections, screw terminals with fol-
lowing characteristics are available:
• Nominal cross section:
0.14 to 2.5 mm
2
(AWG 26...16) for single flexible conductor
0.14 to 0.75 mm
2
for two conductors with same cross section
• Tightening torque:
0.5-0.6 Nm
• Stripping length:
8 mm
For the X1...X6 (RS485 and blocks) connections, screw terminals with following characteristics are
available:
• Nominal cross section:
0.2 to 2.5 mm
2
(AWG 24...12) for single flexible conductor
0.2 to 1.5 mm
2
for two conductors with same cross section
• Tightening torque:
0.5-0.6 Nm
• Stripping length:
10 mm.

Output relays
The device may be confi gured with:
• Two boards with eight command relays KC1-1...KC1-8 and KC2-1...KC2-8 (SPDT, tipo C e SPST-
NO,type A)
• One board with eight command relays KC1-1...KC1-8 and one boardwith with sixteen signalling relay
KS1-1...KS1-16 (SPST-NO, type A with four commons)
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.

Binary Inputs
The input circuits are voltage-free; activation requires the application of a power source, preferably
the same auxiliary voltage present in the switchboard.
The inputs are dimensioned for a wide range of operation and does not require any hw and / or sw
