I/O Extension Card with Analog Inputs (VW3A58201U)
This model includes two 24 Vdc logic inputs, one 24 Vdc open c ollector logic
output, one 0 to 20 mA X-Y configurable analog output, and one bipol ar ±10
Vac analog input. The analog input may be us ed for speed correction with a
tachogenerator, for feedback of the PI fun ction , f or pro cessing of PTC mo tor
protection probes, or for summing the frequency reference.
The figure to the left shows the location of the terminals for this I/O card. The
following tables describe the terminal functions and characteristics. See
page 50 for a summary of configurable I/O functions.
