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.
