34921T Terminal Block

This terminal block with screw- 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
	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 34921T is the only terminal block that provides an isothermal block with temperature reference for thermocouple measurements.

C A U T I O N	When wiring the terminal block via cables to the mainframe, make
	sure the cables are connected to the correct connector. The cables
	provide communication and power to the temperature sensor on
	the 34921T terminal block. If cabling is not correct, an error may
	occur indicating that the 34921A module is not fully operational.

The 34980A Product Reference CD (shipped with the instrument) contains a the 34921T 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.
