Overview

Product overview

Key product information and technical features.

Designed for higher-channel-count thermocouple systems, the sbRIO-9213 adds temperature inputs to mixed-signal test systems. Its non-enclosed construction is intended for OEM integration.

Inputs are multiplexed into one ADC rather than sampled simultaneously. The module provides high-resolution and high-speed timing modes.

Integrated cold-junction compensation.
Open-thermocouple detection.
Anti-aliasing filters.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is sbRIO-9213 the same model documented as NI 9213E?

NI lists sbRIO-9213 part number 781210-01 as the NI 9213E 16-channel, 24-bit thermocouple input board.

Are the input channels sampled simultaneously?

No. The 16 thermocouple channels, cold-junction compensation channel and autozero channel share one multiplexed ADC.

What affects temperature measurement accuracy?

Accuracy depends on thermocouple type, sensor accuracy, measured temperature and cold-junction temperature. Thermal gradients at the terminals also contribute to error.
