12-BIT DIGITAL INPUT
REMARKS
1. As the input signals are at low level, use two parallel micro signal contacts or a twin contact for relay contact
inputs to prevent a contact fault.
2. A transistor of the following specifications should be selected for the open collector signal: Electrical characteris-

3. The control logic is the same as that of the inverter (factory-set to sink). When the logic of the inverter is
changed to source, the option logic also switches to source. For details on changing the control logic, refer to the
inverter instruction manual.
