Power Supply; Safety Wiring - Delta DVP-10PM Instruction Sheet

 Power Supply
DVP-10PM accepts AC power input. When operating the PLC, please note the following
points:
1. The input voltage should be current, and the range is 100 to 240 VAC. Connect the
power supply to the L and N terminals. Wiring AC110V or AC220V to the +24V
terminal or input terminal will result in serious damages on the PLC.
2. The AC power input for DVP-10PM and I/O modules should be ON or OFF at the
same time.
3. Use wires of 1.6mm (or longer) for the grounding.
4. The power shutdown of less than 10 ms will not affect the operation of the PLC.
However, the power shutdown time that is too long or the drop of power voltage will
stop the operation of the PLC and all outputs will go OFF. When the power returns to
normal status, the PLC will automatically resume its operation. (Care should be
taken on the latched auxiliary relays and registers inside the PLC during the
programming).
5. The maximum supply from the +24 V output terminal is 0.5 A. DO NOT connect other
external power supplies to this terminal. Every input terminal requires 6 to 7 mA to be
driven, e.g. the 16-point input will require approximately 100 mA. Therefore, the
+24V terminal cannot output to the external load that is bigger than 400 mA.
 Safety Wiring
In a PLC control system, many devices are controlled at the same time and actions of
any device could affect each other, e.g. breakdown of one device may cause the
breakdown of the entire auto-control system. Therefore, wiring a protection circuit at the
power supply input terminal is highly suggested. See the figure below.
