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.
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:
Bank
0
1
2
3
4
5
6
7
The default configuration is 128 channels of 2-wire switches (128 x 2).
