Measures input voltage signals for CompactDAQ or CompactRIO systems. Models also offer isolation and overcurrent protection for high-voltage applications.

C Series Voltage Input Modules provide an effective combination of channel count, resolution, and speed designed to meet the needs of all types of voltage measurement applications. Isolation on the modules can separate channels from each other, from COM, or from earth ground  for safety, noise immunity, and high common-mode voltage range. Models feature up to 100 V of overvoltage protection for errant signal connection or unexpected outputs to the individual channels. Options include configurable input ranges, output channels, various connectors, and enclosed or non-enclosed modules.
