Hi Savitr -
Yes, it does.
The SCXI-1102 is designed solely for analog voltage inputs. As such, you won't be able to source a voltage to your relay or read from the relay with a digital input. You could, however, set up and Analog Input task to read the voltage across the relay, then interpret that value as "high" or "low" in your software. Simply configure one of the unused input lines on your 1102 to read the voltage.
Your DAQ device also has some available DIO lines, but they're covered up by the connector from your SCXI chassis. You can access them using the SCXI-1180, which breaks these lines out for use on the front panel of the chassis. You will have to refer to the 1102's User Manual to find out which DIO lines it reserves for communication with the DAQ device, then choose one of the unused ones. You can then assign this line to a DAQmx Digital Input task to read the relay's value as a discrete input.
