f The transistor output model of DVP-PM applies “open collector output”. Therefore if Y0/Y1 is set as pulse
output which requires higher operation frequency, the output current passes pull-up resistor has to be
bigger than 0.1A to ensure normal operation of PLC.
1. Diode suppression: Used when in smaller power.
2. Diode + Zener suppression: Used when in larger power and frequent On/Off.
g Manually exclusive output: For example, assume that Y4 and Y5 control the forward running and reverse
running of the motor. In this case, you can design an interlock for the external circuit together with the
PLC internal program to ensure safe operation in case of any unexpected errors.
