External Output - Fujitsu ASUG15LZAS Design & Technical Manual

Use an external output cable with appropriate external dimension, depending on the number of ca-

bles to be installed.

¢ External Input and Output PCB

• A twisted pair cable (22AWG) should be used. Maximum length of cable is 82 ft (25 m).

• Output voltage: High DC 12 V±2 V, Low 0 V.

• Permissible current: 50 mA

• For details, refer to

• When indicator or other components are connected directly:

Example: Rotary SW on External Input and Output PCB is set to "1".
