A.7 Aux Inputs Connector
The Aux Inputs connector provides pins for external voltage inputs,
reserved for future use. The shell lugs of the connector are connected to the
Model 430 Programmer chassis ground. The Aux Inputs connector is a
high density 15-pin D-sub female connector.
Each input pin has a 1 megohm resistor to analog circuit common. The
inputs are differential inputs. Aux Input 1 and Aux Input 2 have a ± 1 V
nominal input voltage range. Aux Input 3, Aux Input 4, Aux Input 5 and
Aux Input 6 have a ± 10 V nominal input voltage range.
