(1) Scaling function
The scaling function is the same that of A/D, D/A combination module
.
4) Wiring
(1) Caution for wiring
•
Make sure that external input signal of the mixture module of AC and analog I/O is not affected by induction noise or
occurs from the AC through using another cable.
•
Wire is adopted with consideration about peripheral temperature and electric current allowance. Thicker than Max. size
of wire AWG22 (0.3
㎟
) is better.
•
If wire is put near to high temp. radiated device or contacted with oil for a long time, it may cause of electric leakage so
that it gets broken or miss-operation during wiring.
•
Be sure to connect with care of polarity while connecting to external 24V DC power supply.
•
In case of wiring with high voltage line or generation line, it makes induction failure so then it may cause of miss-
operation and out of order.
