Module Description
Figure 1-1 shows the Agilent E8462A armature relay multiplexer simplified
block diagram, Option 014 or 015 Terminal Card, and a simple measure-
ment application. Notice the sixteen 100 protection resistors; one in series
with each bank line. Refer to Figure 1-1 for the following description.
Relay Organization The 256 channels of the E8462A Relay Multiplexer are organized into eight
banks with 32 channels per bank. The channels in each bank are as follows:
The default configuration is 128 channels of 2-wire switches (128 x 2).
