The NGI Tech NXI-6201 is a high-precision 4-channel isolated analog output module designed for automated test equipment, BMS validation, and sensor simulation applications. Each of the four channels provides independently configurable voltage or current output at 16-bit resolution, with channel-to-channel isolation ensuring signal integrity in multi-channel test setups.

What output ranges and accuracy does the NXI-6201 offer?

Each channel can be independently programmed for ±5 V or ±200 mV voltage output with an accuracy of 0.03% of reading + 0.02% of full scale, or current output mode with 0.05% + 0.05% F.S. accuracy. The 16-bit DAC resolution provides 65,536 discrete output levels per channel, suitable for precision shunt simulation, Hall sensor emulation, and BMS cell voltage simulation where fine granularity is essential.

How does the NXI-6201 integrate into a test system?

The module communicates over Ethernet LAN with support for three industry-standard protocols: SCPI for direct instrument control, Modbus RTU for PLC and SCADA integration, and CANopen for automotive test environments. NGI Tech provides DLL driver files for C++, .NET, VB, and Delphi, plus LabVIEW and C# development examples, enabling rapid integration into custom test sequencers. The module can be powered via a standard 12 V DC adapter for standalone bench-top use or installed in an NXI-F1000 series chassis for multi-card synchronized operation.

What applications benefit from channel-to-channel isolation?

The per-channel galvanic isolation prevents ground loops and cross-channel interference when simulating multiple independent sensor signals into a device under test — a critical requirement for BMS testing where each cell input must float independently. The same isolation enables mixed-signal test setups where different channels drive loads at different reference potentials without interaction.
