NXI-4101-32
NXI-4101 High-Speed Digital I/O
Programmable 32-channel digital I/O module NXI-4101 with 40MHz PWM
The NXI-4101-32 is a programmable high-speed digital I/O module featuring 32 independent channels. Logic levels are optionally configurable to 3.3V or 5V CMOS standards. At 5V, the module provides an output drive capability of 32mA, while 3.3V operation supports up to 24mA per channel. It supports PWM outputs with a maximum frequency of 40 MHz alongside precise pulse and frequency measurements. An integrated 16 MB output RAM allows for complex signal sequences with a synchronous time tolerance of 1.25 ns. For data acquisition, an input FIFO with a capacity of 512 samples is provided. Communication is handled via LAN using the Modbus-RTU protocol with a 12V DC power supply. Typical applications include automotive ECU testing and high-speed signal detection in industrial production.

NXI-4101-32: High-Speed Digital I/O Module for Precise Signal Processing in Industrial Test Engineering
The NXI-4101-32 is a powerful 32-channel digital I/O module for precise signal processing in research, development, and industrial quality assurance. Combining a high channel count, flexible level selection, and extremely low synchronous timing tolerance, the module is ideal for demanding test and automation tasks.
With a synchronous timing tolerance of only 1.25ns and software-selectable CMOS levels of 3.3V and 5V, the system enables reliable real-time signal acquisition in complex test environments.
This allows time-critical digital signals to be measured, generated, and processed with high accuracy while reducing overall system complexity in the test setup.
