About National Instruments Current Input Module for Remote I/O REM-11102:
Provides current input channels for remote I/O systems. Remote I/O modules must be used with a supported NI real-time controller. The Current Input Module for Remote I/O features 2-, 3-, and 4-wire spring terminal connection methods, a built-in power supply for sensors, a selectable input range (0 mA to 20 mA, 4 mA to 20 mA, and ±20 mA), and simultaneous sampling. A remote I/O system consists of an EtherCAT bus coupler and individual modules mounted on a DIN rail. You control the Current Input Module for Remote I/O from a real‐time controller, such as a CompactRIO Controller or an Industrial Controller. You can use remote I/O hardware to add low‐cost I/O for simple tasks while your controller handles advanced tasks such as image processing, motion control, and high‐speed or specialty measurements.
