6) 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.
(2) Wiring example
a) Analog input
b) Analog output
*1 : Be sure to use two-core twisted shield wire.
* Be careful to use that analog output is 1 channel.
