Digital I/O Module for SCXI


32-Channel, Input (TTL/CMOS), Digital I/O Module for SCXI—The SCXI‑1162 is an optically isolated digital input module for SCXI. It interfaces to field digital logic signals, such as TTL and CMOS, in which high-common-mode voltages can be present. The optical isolation of the SCXI‑1162 eliminates ground-loop problems and isolates the host computer from damaging voltages. The module is programmed by the DAQ device serially over the SCXIbus. You can, therefore, easily integrate SCXI‑1162 modules into existing SCXI systems without additional DAQ devices or cabling. The SCXI‑1162 can also operate in parallel mode when cabled directly to a digital I/O device.
