기능

• The power supply must be a 115 V external power supply (70 V minimum, 132 V maximum).
• Altivar ATV61/ATV71 -115 V Logic Input Adapter
• This adapter is used to connect 115 V ac logic signals to the logic inputs of drives (AVT61/ATV71) or I/O expansion cards.
• 7 logic inputs (0.22 μF 60 Hz capacitive impedance) connected to logic signals: - Maximum current: 200 mA - Response time: from state 0 to 1 in 5 ms, from state 1 to 0 in 20 ms - Logic state 0 for voltages below 20 V, logic state 1 for voltages between 70 V and 132 V
