Description
B&R X20AIB744
Technical Specifications: Multiple analog input channels Supported signal types: 4-20mA, 0-20mA, ±10V Conversion resolution: 12-bit analog to digital converter Galvanic isolation between field side and bus side Bus interface: X2X Link Protection class: IP20 Operating temperature: 0℃ to 55℃ Certifications: CE, UL, ATEX Zone2
Functional Features: Multi-channel analog signal acquisition for field process transmitters. Support current and voltage analog signal types. 12-bit high precision analog to digital conversion. Per-channel diagnostics to detect wire break, short circuit and sensor fault. Galvanic isolation to suppress ground loop interference. LED indicators for module run status and fault alarm. Hot swap capability for online module replacement. Digital filtering function for stable measurement data.
Application Scenarios: Plastic extrusion machine process monitoring, packaging machinery pressure and temperature measurement, water treatment process control, food and beverage production line, small chemical auxiliary control system, test bench data acquisition.
Performance Parameters: High measurement accuracy for analog process signals. Configurable digital filter to reduce signal noise. Fast data update over X2X backplane bus.
Material Composition: FR4 high reliability industrial printed circuit board. 12-bit analog-to-digital conversion chips. Signal conditioning and isolation components. Flame retardant plastic module housing. Gold plated X2X backplane connector. Screw terminal block for field transmitter wiring.
Structural Features: Compact X20 segmented modular form. Front panel LED indicators for module running and fault status. Side X2X Link backplane connector for bus connection. Screw terminal block for analog sensor wiring. Stacking installation on X20 bus base module.
Working Principle: Analog signals from field transmitters enter module through screw terminals. Signal conditioning circuit adjusts signal range and filters interference. Analog to digital converter converts analog measurement signal to digital value. Galvanic isolation blocks electrical noise and ground loop from field side. Process data and channel fault information are transmitted to X20 controller via X2X Link bus.
Installation Requirements: Mount module on X20 bus base module. Field analog wiring must use shielded twisted pair cable. Analog signal cables must be separated from high voltage power cables. Install inside IP20 control cabinet. Tighten terminal screws to specified torque.
Usage Notes: Set channel signal type to match connected field transmitter. Carry out signal calibration after module installation. Single end ground for cable shielding layer. Cut power supply before modifying field wiring.
