Overview

Product overview

Key product information and technical features.

The PXI-4224 combines isolated analog acquisition and signal conditioning in a PXI module. Channel-to-channel isolation supports measurements where signals have differing common-mode potentials, within the specified isolation limits.

NI identifies isolated thermocouple measurements, multichannel data logging, and fuel cell and battery testing as applications. NI-DAQmx provides hardware configuration and measurement automation.

Built-in signal conditioning for analog input measurements.
Programmable gain settings on each channel.
Channel-to-channel isolation rated at 60 VDC (42 Vrms), CAT I.
TB-2725 terminal-block connectivity for eight signal pairs and external triggering.

FAQ

Product-specific questions

Product-specific answers based on available technical information.

Is the PXI-4224 rated for 333 kS/s?

No. NI specifies a maximum sample rate of 200 kS/s for the PXI-4224.

Which terminal block is documented for the PXI-4224?

NI documents the TB-2725, with 16 screw terminals for eight input signal pairs and an SMB connector for external triggering. Accessory inclusion is not established by this catalog record.

Does the isolation rating mean it measures 60 V directly?

No. NI lists ±10 V and ±1 V input ranges separately from the 60 VDC channel-to-channel isolation rating.
