32-Channel, Input (240 V), Digital I/O Module for SCXI—The SCXI‑1162HV is an optically isolated digital input module for SCXI. This module senses the presence of a wide range of AC or DC signals, from digital logic level signals up to 240 VAC/VDC signals. The optical isolation of the SCXI‑1162HV 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‑1162HV modules into existing SCXI systems without additional DAQ devices or cabling. The SCXI‑1162HV can also operate in parallel mode when cabled directly to a digital I/O device.
