Note 1: The role of the a-contact for variable motor control is double-loading / non-voltage closing, and the role of the b-contact for dynamic brake contact is 1 × loading / non-voltage closing.
Note 2: A common DC motor is compatible with motor load for DC2 class (shunt motor start/stop) and DC4 class (series-wound motor start/stop) from JEM1038.
Note 3: The *1 allowed energization time is 30 seconds. When using for inching, use the rated operating current for common DC motors.

Note 1: The table above indicates the guideline values of characteristics when using a 200 V AC coil during AC operation (DU-N□).
Note 2: Operating voltage is the average value during AC operation (at 60 Hz). For coils other than 200 V AC, purchase approximately proportional to the voltage.
Note 3: Input and power consumption are shown as average values. Nearly identical even for coils other than 200 V AC.
Note 4: Coil current is the average value when applying 220 V 60 Hz during AC operation. When using a coil other than the 200 V AC coil, divide the constant input by the coil voltage to find the coil.
Note 5: Operating time is the value when applying 220 V 60 Hz during AC current. Nearly identical even for coils other than 200 V AC.
