The information in this section is arranged as follows:
4.2 Power limits:
Summarizes the maximum power
limits of the Model 7012 matrix card assembly.
4.3 Mainframe control of matrix card:
Summarizes
programming steps to control the matrix card
from the Model 7001 Switch System mainframe.
4.4 Multiplexer switching examples:
Provides some
typical applications for using the Model 7012.
4.5 Measurement considerations:
Reviews a num-
ber of considerations when using the Model 7012

4.2 Power limits
CAUTION
To prevent damage to the card, do not
exceed the maximum signal level
speciÞcations of the card.
Maximum signal levels
To prevent overheating or damage to the relays, never
exceed the following maximum signal levels:
DC signals: 110V between any two pins (termi-
nals), 1A switched, 30VA (resistive
load)
AC signals: 125V rms or 175V AC peak be-
tween any two pins (terminals), 1A
switched, 60VA (resistive load)
4.3 Mainframe control of matrix card
The following information pertains to the Model 7012
matrix card. It assumes that you are familiar with the
operation of the Model 7001 mainframe.
If you are not familiar with the operation of the main-
frame, it is recommended that you proceed to Getting
Started (Section 3) in the Model 7001 Instruction Man-
ual after reading the following information.
