9.3.4 Connecting External Instruments
Using the analog I/O terminal block, connect external instruments for analog input
and output. For details on how to wire terminals, refer to the "Analog I/O Terminal
Wiring Diagrams."
Wiring
Follow the procedure below to wire analog I/O.
The following describes how to wire the KV-AD4.
• Use 2-core twisted pair cable for the analog signal cable.
• When wiring the terminals, use rounded or forked crimp terminals of width
6 mm. Wiring terminals without crimp terminals is likely to result in faulty
contact, and prevent data from being transmitted correctly. Use M3.0
screws on the terminal blocks on the KV-AD4/DA4.
• Wire the AC power cable and analog signal cable separately. Do not bundle
these cables together.
• With the KV-AD4, connect the shielded cable to the input side, and with the
KV-DA4, connect to the load side.
Note: When mounting the KV-AD4/DA4 at a location that is likely to be influenced
by electrical noise, ground using a grounding resistance of 100 Ω max.
1. If the KV-AD4 is already connected
to a KV-10 to 80 CPU, turn it OFF
and then disconnect it from the
CPU.
2. Remove the protective cover of the
analog input terminal block. Hold
the left and right sides of the cover
as shown in the figure, and lift up to
remove.
3. Attach the crimp terminals of the signal cable to the terminals.
Wire the cables correctly. Wiring the cables to the incorrect terminals may
result in malfunction.
• Loosen the terminal screw with a
screwdriver, and then insert the
crimp terminal.
Then, firmly tighten the terminal
screw.
➮ For details on wiring, refer to
"KV-AD4 Analog Input Terminal"
on page 1-346 and "KV-DA4
Analog Output Terminal" on
page 1-347.
4. Attach the cover to the analog input
terminal block.
