National Instruments 780493-02 Conformal-Coated C Series Temperature Input Module
The National Instruments 780493-02 (NI-9213) is a high-density, 16-channel C Series temperature input module engineered for large-scale thermocouple measurements in harsh environments. Featuring a protective conformal coating, this variant guards sensitive electronics against moisture, corrosion, and airborne debris. Equipped with a 24-bit analog-to-digital converter, a ±78.125 mV voltage range, and sampling rates up to 75 S/s per channel, it supports all standard thermocouple types while maintaining a compact footprint within CompactDAQ and CompactRIO chassis.
Built to ensure measurement integrity and system safety, the 780493-02 incorporates built-in anti-aliasing filters to eliminate high-frequency noise interference. Onboard cold-junction compensation corrects for reference junction thermal drift, while open-circuit detection immediately alerts operators to broken or disconnected sensors. Each channel undergoes NIST-traceable calibration and features 250 Vrms channel-to-earth ground isolation, protecting connected equipment from high-voltage transients and eliminating common-mode ground loops.
Engineers utilize the 780493-02 across industrial automation, environmental monitoring, product validation, and laboratory research. Its 24-bit resolution and wide operating temperature range (-40°C to +70°C) make it ideal for capturing subtle thermal gradients in demanding applications such as multi-zone HVAC testing, semiconductor characterization, process control, and thermal profiling in high-humidity or condensation-prone environments.
