Each System 10
Bridge Completion Connector
attaches directly to the rear I/O
CONNECTOR of the Model 10A73-4.
Remove the top plate of the connector. Inside are four sets of labelled screw termi-
nals, corresponding to the 10A73-4's four input channels. You will connect your gage
wires directly to these terminals and, if necessary, interconnect certain terminal pairs
by means of jumper wires. All gage leads should be securely clamped by means of
the two cable clamps.
Fig. 2 shows per-channel connections between external strain-gage configurations
and the respective System 10 Bridge Completion Connectors.
NOTE: Unlike the Model 10CJB-4, the Bridge Completion Connectors DO NOT PER-
MIT MIXING OF CONNECTED GAGE CONFIGURATION TYPES. That is, all gage con-
figurations connected to the same Bridge Completion Connector must be of the same
appropriate type (e.g., 120-
Ω
1/4-bridge, 1/2-bridge, etc.).
When input connections involve pairs of EXCITATION, SENSE, and/or SIGNAL lines,
these should be twisted pairs within the input cable. While it is desirable to shield
such pairs individually (as shown in Fig. 2), this is not necessary; an overall cable
shield is acceptable.
Note too that the full-bridge input connections given in Fig. 2(e) are to be used if one
or more of the 10A73-4's other inputs derives from a less than full-bridge configura-
tion. If all four inputs originate from full-bridge configurations, no completion circuitry
is required (see Section 2.c and Fig. 4).
