34921T Terminal Block - Agilent Technologies 34921A User Manual

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.
The 34921T is the only terminal block that provides an isothermal
block with temperature reference for thermocouple measurements.
The temperature sensor is located on the bottom side of the PC board
as shown below. Also shown are two holes that you can use for connecting
an external temperature reference to the terminal block.

All modules that connect to the internal DMM are interlock
N O T E
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

When wiring the terminal block via cables to the mainframe, make
C A U T I O N
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.
