Working Principle
Receives digital measurement command signals from host PC over USB bus. Distributes clock, trigger, and power signals to all installed C Series I/O modules via internal backplane bus. Aggregates analog/digital sampled data from modules, buffers data internally, and transmits consolidated measurement datasets back to host computer for real-time analysis and storage. Internal fault monitoring circuit continuously scans slot power rails and module communication links to flag hardware errors.
Advantage Highlights
- Modular expandability with full C Series module compatibility (voltage, thermocouple, strain, digital I/O, relay)
- USB bus-powered design eliminates separate external DC power supply for low-channel test setups
- Compact footprint minimizes bench/control cabinet space occupation
- Industrial-grade environmental tolerance for factory test stations
- Native multi-language programming library support for automated test systems
Applicable Industries
Automotive component testing, aerospace sensor calibration, consumer electronics quality inspection, academic laboratory measurement, renewable energy power monitoring, medical device validation
Installation Requirements
- Mount unit on horizontal bench surface or standard 35 mm DIN rail with factory-supplied mounting clip
- Maintain minimum 20 mm clearance on all ventilation sides for passive heat dissipation
- Connect shielded USB cable (maximum length 5 m) directly to host PC USB 2.0 port; avoid USB hubs for high-speed sampling
- Earth ground chassis mounting bracket to facility protective earth for EMC noise suppression
- Insert C Series modules fully until mechanical locking tab engages to maintain backplane contact integrity
Usage Precautions
- Do not operate unit in environments with condensation or direct liquid exposure
- Do not populate slots with modules exceeding combined 500 mA total current draw
- Disconnect USB power before inserting/removing modules if operating at temperature extremes (>40 °C)
- Avoid deployment near high-current AC drive or welding equipment without shielded cabling
- Store unit in dry, temperature-controlled cabinet when not in long-term use
