• A twisted pair cable 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 "Setting of external input and output" on page 05-15.
• When indicator or other components are connected directly:
Example: Rotary SW on External Input and Output PCB is set to “1”.
