10-2. External output
Use an external output cable with appropriate external dimension, depending on the number of
cables to be installed.
¢ Indoor unit
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 25 m.
• Output voltage: High DC 12 V ± 2 V, Low 0 V.
• Permissible current: 50 mA
• For details, refer to Chapter 10-3.
 When indicator, etc. are connected directly
Example: Function setting 60 is set to "00"
LED
 When connecting with a device equipped with a power supply
Example: Function setting 60 is set to "00"
¢ External input and output PCB
