Calculating Input Power Requirements for IC693PWR331
Use the following procedure to determine input power requirements for the 24 VDC High Capacity
Power Supply:
Ŷ Determine total output power load from typical specifications listed for
individual modules at the end of this chapter.
Ŷ Multiply the output power by .5 to determine the input power value.
Ŷ Divide the input power value by the operating source voltage to determine the
input current requirements
Ŷ Use the lowest input voltage to determine the maximum input current
Ŷ Allow for start-up surge current requirements
Ŷ Allow margins (0% to 20%) for variations
Field Wiring Connections to the DC Input-Only Power Supplies
DC Power Source Connections
The + and - wires from the DC power source connect to the top two terminals on the
terminal strip. The + wire should be connected to the top terminal screw, and the - wire to
the second screw (counting from the top down). The ground connection connects to the
third screw. This connection scheme is clearly marked on the front of these power
supplies.
Isolated 24 VDC Supply Output Connections
The bottom two terminals of the power supply terminal strip provide connections to the
Isolated +24 volt DC output which can be used to provide power for external circuits
(within power limitations of the supply).
Caution
If the Isolated 24 VDC supply is overloaded or shorted, the
Programmable Logic Controller will stop operation.
