2 TRANSDUCER CONNECTIONS
2.a STANDARD CABLING
The Model AA41’s rear I/O CONNECTOR mates with the special AA41 CONDITIONER
CONNECTOR, via the cable connections shown in Fig. 3.
Mounted on the internal
board of the connector assembly (shown in Fig. 2) is a block of ten clearly
labelled screw terminals for each of the AA41's four possible input channels.
To access the connector board, simply remove the screws that hold together
both halves of the connector housing. Use the two internal clamp bars to secure
transducer cables once all leads have been connected.
The connector assembly's mounting screws are designed to secure the connec-
tor to the rear of the system mainframe and to provide a solid GROUND CON-
NECTION for cable “shields” via the two L-shaped ground lugs. An offset in the
mounting holes ensures that the connector cannot be attached upside down.
Fig. 3(a) shows recommended cabling for intrinsically grounded transistor or logic-cir-
cuit drivers
; Fig. 3(b), for pulse transformer transducers with two-wire isolated wind-
ings (tachometers, turbine flowmeters, etc.); and Fig. 3(c), for
“zero-velocity” (true
digital output) sensors requiring 10-V excitation
