System Power Supply (AC/DC)

One System Power Supply (AC/DC) is sufficient for many small systems. The power supply provides 1.25 A of LocalBus power, enough for:

• 8 discrete I/O cards

  or

• 8 analog I/O cards

  or

• 4 serial I/O cards

  or

• 4 Series 2 H1 cards

Refer to the installation worksheets for complete information on calculating system power for all I/O card combinations.

For systems that require additional power, use another System Power Supply (AC/DC) for load sharing. For systems that require redundant power, connect a second System Power Supply (AC/DC).

Other options for systems that require additional power are the System Power Supply (Dual DC/DC) with a bulk power supply. These options do not require an additional two-wide carrier and are good choices when future expansion is anticipated.
