Industrial DAQ

16-channel industrial data acquisition platform supporting RTD, 4-20mA sensors and high precision analog measurement. Engineered for industrial environments with robust EMI filtering and galvanic isolation.

Specifications

Channels

16 differential analog input channels with independent configuration

Resolution

24-bit delta-sigma ADC for high precision measurement

Sensor Support

RTD Pt100/Pt1000, 4-20mA, 0-10V, thermocouples

Sampling Rate

Up to 100 Hz per channel simultaneous sampling

Isolation

3kV galvanic isolation on all input channels

Communication

Modbus RTU, CAN Bus, Ethernet connectivity options

Architecture

The Industrial DAQ features a distributed architecture with per-channel signal conditioning and centralized data processing. Each channel includes precision instrumentation amplifiers, EMI filtering, and isolation. The ARM-based gateway processor handles Modbus/CAN communication and data logging.
