Chapter 7 Usage of Various Functions

(1) Scaling function
The scaling function is the same that of A/D, D/A combination module.
(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.
