I/O Extension Card with Analog Inputs (VW3A58201U)

This model includes two 24 Vdc logic inputs, one 24 Vdc open collector logic output, one 0 to 20 mA X-Y configurable analog output, and one bipolar ±10 Vac analog input. The analog input may be used for speed correction with a tachogenerator, for feedback of the PI function, for processing of PTC motor 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.
