Power Budget

Use the power budget to calculate the maximum number of devices that the power supply can supply. If more devices are used, additional power supplies must be added to the I/O bus.

The power supply delivers an output voltage of 24 VDC ± 1 V at an output current of about 1.25 A. The power supply can supply power for loads up to 30 W.

Note:

The number of devices that the power supply can supply is 30 W based on the individual wattage requirements of each device installed in a system.

To determine the number and position of the power supplies, use the following power budget table.
