Key product information and technical features.
This module senses signal presence rather than measuring analog voltage amplitude. It supports serial programming over the SCXIbus or parallel operation through a directly connected digital I/O device.
The SCXI-1326 terminal block provides screw-terminal field connections. For the SCXI-1162HV, CHAN terminals carry input signals, GND provides the ground reference, and VCC terminals are unused.
