5.1.2
Cable
The
⑦
(yellow) wire inside the shrinkable tube is not
short-circuited with any other wire.
CAUTION
• The
⑦
(yellow) wire cannot
be short-circuited with any
other wire or it will cause
damage and malfunction to
the AD panel.

The maximum absolute rating is 50 V for voltage and 100 mA for current.
The recommended value is half or less of the rating.
In case of adding an inductor (e.g., relay), install a noise limiter (approx. 33 Ω + 0.1 μF), diode, or
the like.
*3: Analog output (1
～
5V)
