4Low Frequency Multiplexer Switch Modules

34924T Terminal Block

This terminal block with solder- type connections is labeled with the model number and the abbreviated module name. In addition, space is available on the label for you to write the slot number.

	N O TE	All modules that connect to the internal DMM are interlock
	N O TE	protected. This means that when an installed module is exposed (no

		terminal block or cable is connected), the Analog Bus relays are
		open and disconnected from the Analog Buses. See page 96 for
		further information.

The 34980A Product Reference CD (shipped with the instrument) contains a the 34924T Wiring Log for you to document your wiring configuration for this module. You can open the wiring log file in Microsoft® Excel® or Adobe® Acrobat® format.
