NXI-6700-4
NXI-6700-4 DC Voltage Module
Precise 4-channel DC voltage measurement module NXI-6700-4 up to 600V.
The NXI-6700-4 is a high-accuracy module for the synchronous acquisition of DC voltages across four channels. It provides three selectable measurement ranges of ±6V, ±60V, and ±600V with a resolution of up to 0.1mV. The basic accuracy of the device is specified at 0.025% + 0.025% of the full scale. To optimize testing workflows, three adjustable reading rates are available with up to 50 samples per second. Each channel features its own electrical isolation to ensure measurement safety in demanding environments. Communication is handled via LAN or CAN interfaces using Modbus-RTU, SCPI, or CANopen protocols. The module is designed for use in NXI-F chassis and requires a 12V DC power supply. Typical applications include automotive electronics testing, home appliances, and integrated test systems.

NXI-6700-4 DC Voltage Measurement Module: Precision Measurement for Industrial Test Systems
The NXI-6700-4 is a compact, multi-channel DC voltage measurement module designed for highly accurate measurement tasks in modern industrial test environments. It was specifically developed for use in the NXI-F1000 chassis or in standalone operation and enables synchronous acquisition across four measurement channels while requiring minimal space.
By combining high basic accuracy, galvanically isolated channels and a compact single-slot design, the module is ideal for automated test systems where signal integrity, scalability and system efficiency are key priorities. This allows complex test setups to be implemented cost-effectively and optimized over the long term.
