Card Connections and Installation
3.4
Typical connection schemes
Paragraphs 3.4.1 and 3.4.2 show how the Model 7013
could be connected to a system that activates external
devices and circuits. These are connection schemes for
the relay switching example that is explained in para-
graph 4.4.2 and illustrated in Figure 4-4.
Paragraph 3.4.1 describes a connection scheme using
the multi-pin connector card of the Model 7013-C,
while paragraph 3.4.2 describes a connection scheme
using the screw terminal connector card of the Model
7013-S. Keep in mind that these are only examples to
demonstrate a couple of ways to wire a system. Con-
nection details for both connector cards are provided in
paragraph 3.3.
If adding more Model 7013 cards to a system, simply
wire them in the same manner as the first. Remember
that two Model 7013 cards installed in the same main-
frame are electrically isolated from each other. When
two or more Model 7001 mainframes are used, they
must be connected together (see Model 7001 Instruc-
tion Manual).

3.4.1 Connection scheme for Model 7013-C
Figure 3-8 shows how external connections can be
made to the system using the multi-pin connector card.
The Model 7011-MTC-2 cable assembly is cut in half to
provide a cable that is unterminated at one end. The
unterminated end of the cable can then be hard-wired
directly to the external devices and power supplies.
The other end will then mate to the Model 7013-C
switch card assembly.
3.4.2 Connection scheme for Model 7013-S
Figure 3-9 shows how external connections can be
made to the system using the screw terminal connector
card. Single conductor (#16-22 AWG) connections are
made directly from the screw terminals of the connec-
tor card to the external devices and power supplies.
