Auxiliary I/O Card Installation (Optional)
Standard Input Connections
By making the connections shown in
, the indicator on the operator console is
active when the switch is closed. The input circuitry is active low and does not require 12
VDC applied externally. The components shown to the right of the switch are part of the
AUX I/O card.
Figure 20: Standard Input Connection
Isolated Input Connections
To activate the isolated inputs, a current of 5-10 mA is typically required. (See
.)
A 1 k
resistor in parallel with the inputs can be used with an external resistor to create
the proper divider.
