32-channel universal high-speed DAQ
Designed and manufactured in India
UniDAQ for Mixed-Sensor Measurement and Synchronized Logging
UniDAQ is a 32-channel universal data acquisition system for dynamic and laboratory measurements. It combines dedicated voltage, current, thermocouple, and strain gauge input groups under one acquisition engine, Ethernet communication layer, and PC software platform.

Channel architecture
Four optimized input groups in one platform
UniDAQ separates the 32 channels into four electrically and functionally optimized measurement groups: voltage, current, thermocouple, and strain gauge. Each group is configured for its signal type while sharing common acquisition, memory, Ethernet, and software layers.
8 voltage channels
Differential voltage inputs with software-selectable ranges including +/-100 mV, +/-1 V, +/-5 V, and +/-10 V.
8 current channels
Dedicated industrial current inputs for 0-20 mA and 4-20 mA measurement with engineering-unit scaling.
8 thermocouple channels
Configurable J, K, T, E, N, R, S, and B thermocouple channels with local cold-junction compensation.
8 strain gauge channels
Quarter, half, and full bridge support with configurable gauge factor, bridge balance, tare, and shunt calibration provision.
Customizable input connectors
Input connector type, pin grouping, terminal style, and channel labelling can be customized to match your sensor wiring and installation requirements.
Technical specification
High-speed universal acquisition engine
The customer specification includes both 1 MS/s system sampling and 1 kHz maximum sampling per channel. UniDAQ therefore defines a 1 MS/s aggregate high-speed acquisition engine with configurable logging up to 1 kHz per configured measurement channel.

Software and integration
PC monitoring, configuration, logging, and export
UniDAQ is specified with Windows and Linux PC software support, Ethernet communication, real-time monitoring, channel configuration, continuous or test-based recording, and data export for analysis.
Live monitoring
Numeric values, multi-channel trend graphs, and channel status visibility during acquisition.
Channel setup
Configure type, range, sampling rate, filtering, scaling, gauge factor, excitation, and calibration.
Export and analysis
CSV and spreadsheet-compatible export with min/max/mean/peak-to-peak and basic filtering support.
Integration ready
Interface/API or export provisions for MATLAB, LabVIEW, OPC, ActiveX, and documented protocol access.
Universal 32-channel DAQ for mixed voltage, current, thermocouple, and strain measurements
UniDAQ is intended for laboratories, validation benches, industrial test rigs, and mixed-sensor acquisition systems where multiple signal types must be synchronized and logged through one platform. The architecture supports voltage measurement, 4-20 mA current loops, thermocouple temperature acquisition, strain gauge bridge measurement, Ethernet PC control, calibration, and export workflows.
