5 Using Load Cards and Loads

Using the Agilent E6177A 24-Channel Load Card

The Agilent E6177A 24-channel medium-current load card is

intended to be used with loads mounted inside the Switch/Load

Unit. Figure 5-27 shows a block diagram of the E6177A.

• The card is one slot wide. “Card Location Recommendations"

• The card type is 05

. “Load Card Type and Configuration ID"

• The factory default configuration is explained in “Selecting a

Power Supply Configuration" on page 41.

• The Common line (PwrX where X is the channel number) on

the input is brought back out to the input, allowing each

channel to operate in a general-purpose (GP) configuration.

This lets you switch in a special external power supply while

bypassing the power bus of the SLU, for example. “Using the

Power Switches as General Purpose Relays"

• A nine-inch by four-inch area of sheet metal is left open on

the front of the card to allow room for mounting small loads.

“Connecting Loads"

• Each channel is capable of up to 2A continuous carry

current.

• The card is not equipped for current sensing

• There is not any flyback voltage protection
