Provides thermocouple input channels for remote I/O systems. Remote I/O modules must be used with a supported NI real-time controller.

The Temperature Input Module for Remote I/O features a features a thermocouple input range of ±100 mV and a voltage input range of ±5 V. It also has an adjustable filter time for improved measurement quality and optional external CJC or PT100 RTD measurements.A remote I/O system consists of an EtherCAT bus coupler and individual modules mounted on a DIN rail. You control the Temperature 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.
