Wiring of analog output terminal
If the analog output terminals AO1 and AO2 are connected to analog meters, then various kinds of physical values can
be measured. The jumper can select current output (0/4~20mA) or voltage output (0/2~10V). The wiring is as follows:
Fig.4-6 Wiring of analog output
Notes:
1.When using analog input, a common mode inductor can be installed between VCI and GND or CCI and GND
2.The analog input voltage is better under 15v.
3.Analog input and output signals are easily disturbed by noise, so shielded cables must be used to transmit these
signals and the cable length should be as short as possible.
4.The analog output terminal can stand the voltage under 15v
Wirings of multiple function input terminal and
operation terminal
SV100 multi-function input terminal uses a full-bridge
rectifying circuit as shown in Fig.4-7. PLC is the
common terminal of terminals X1~X7, The current
flows through terminal PLC can be pulling current and
the feeding current. Wiring of X1~X7 is flexible and the
typical wiring are as follows:
1.Dry contacts method
1) Analog differential voltage input, the wiring is as in
fig.4-7.

supply
2) If an external power supply is used (The power
supply must satisfy the UL CLASS 2 standard and a 4A
fuse is must between the power supply and terminal), the
