Analog Voltage Input Module

See Analog Voltage Input Module Products

The module that connects an input device, such as a panel or a sensor, to a programmable logic controller (PLC), a device used to control automated manufacturing processes. When Six Sigma or other quality improvement methods are applied to manufacturing environments, input modules are evaluated as a potential source of error.

A variety of analog and digital signal conditioning modules form the basis of the SCXI system. Analog input modules amplify, isolate, filter, and multiplex input signals from thermocouples, strain gauges, RTDs, thermistors, millivolt sources, voltage sources up to 250 Vrms, and current sources. Mix and match any combination of analog input, analog output, digital I/O, and switching modules to meet your application requirements.


This is a multichannel voltage module capable of measuring 16 channels of DC voltage on a single unit.
