CNX Analog Output Expansion
Card: CNXAO-8
Description
Functional Description
The CNXAO-8 Analog Output Expansion Card provides eight analog output
connections with a maximum voltage span of +/-12 VDC and 80 mA maximum
source/sink current. The analog output connections are arranged as two groups of
four with a multi-turn span adjustment for each group. Each group has a jumper (X1
and X2) to select whether the outputs power up/reset at 0% or 50%. Furthermore,
each output has a multi-turn offset potentiometer (pot) to position span as required.
Physical Description
The CNXAO-8, shown below, is a circuit board fastened to an aluminum faceplate.
The card is manufactured to easily fit into an unoccupied slot in a Crestron CNX
Generation Control System.
CNXAO-8 Faceplate
The faceplate contains two identical 5-position mini-Phoenix type connectors
(labeled A and B). There are four analog output pins and one common ground pin
per connector. Silk screening is applied to the faceplate; pins are labeled A1 through
A4 and B1 through B4. Common ground pins are labeled with a G. All pots are
accessible from outside the CNX Generation Control System through holes in the
faceplate.
