C-Series Module, Current Input

Current input modules measure analog current signals, commonly used in industrial sensors and control systems. Many transmitters output current in standard ranges such as 4-20 mA.

Key specifications include channel count, resolution, measurement ranges, and accuracy. Isolation is often included to protect the system from ground loops common in current loops.

These modules are widely used in process control and industrial monitoring, where current signals are more robust over long cable runs than voltage. They integrate easily into CompactDAQ or CompactRIO systems for reliable sensor interfacing.
