32-Channel, Output (TTL/CMOS), Digital I/O Module for SCXI—The SCXI-1163 is an optically isolated digital output module for SCXI. The SCXI-1163 interfaces to field digital logic signals to eliminate ground-loop problems and isolate the host computer from damaging voltages. This module is programmed serially over the SCXIbus. You can, therefore, easily integrate SCXI-1163 modules into existing SCXI systems without additional DAQ devices or cabling. The SCXI-1163 can also operate in parallel mode when cabled directly to a plug-in digital I/O device.
