NI 9219 belongs to NI C Series hardware platform, compatible with CompactDAQ and CompactRIO chassis. It integrates four independent 24-bit delta-sigma ADC with simultaneous sampling function, max sampling rate 100 S/s per channel. Each channel can be individually configured for different measurement types. It has built-in voltage/current excitation and cold-junction compensation for thermocouple acquisition.

This module supports multiple measurement modes: voltage (±60V, ±15V, ±4V, ±1V, ±125mV), current (±25mA), thermocouple, 2/3/4-wire RTD, resistance measurement, quarter-bridge, half-bridge and full-bridge strain gauge / load cell signals. It supports IEEE 1451.4 TEDS sensor automatic identification. 250 Vrms channel-to-channel isolation effectively suppress ground loop interference and improve safety for mixed-signal testing. Front side adopts spring push-in terminal connectors for convenient wiring.

Full protection includes overvoltage protection, ESD protection and transient surge protection. Operating temperature range -40℃ ~ +70℃. It works with LabVIEW software for data acquisition, online analysis, logging and alarm functions. It is commonly used for material tensile test, structural strain test, temperature distribution test and multi-type sensor mixed acquisition.

NI 9219 is a mature NI test module. When the original module fails, replacing it with identical NI 9219 can reuse existing C Series chassis, wiring, sensors and LabVIEW measurement project without redevelopment. Technicians install the module into chassis, configure measurement channels and verify sensor reading, so the multi-sensor measurement system resumes operation and reduces downtime.

Before shipment, every NI 9219 undergoes comprehensive functional inspection including power-on self-test, ADC calibration, channel isolation test, multi-mode signal acquisition verification and TEDS communication test. All products come with 12-month warranty. Our automation technical team provides remote support for chassis installation, wiring guidance, LabVIEW programming and sensor troubleshooting. Fast global shipping available for urgent maintenance orders.

For automation maintenance engineers and system integrators, NI 9219 is reliable spare universal analog input module for NI CompactDAQ / CompactRIO test systems. It restores multi-sensor mixed signal acquisition capability, extends service life of test assets and avoids high-cost whole measurement system renovation.
