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 "Combination of external input and output" on page 20.
• When indicator or other components are connected directly:
Example: Rotary SW on External input and output PCB is set to “1”.
