ABB UA C326 AE01 Analog/Digital I/O Card

Description

ABB UA C326 AE01 Analog/Digital I/O Card is a multi-functional input/output card designed for industrial automation and drive system applications. Based on comparable ABB control card specifications, it features integrated analog and digital signal handling capabilities, including 4 analog input (AI) channels and 2 analog output (AO) channels. AI channels support 0-10V DC or 4-20mA DC signals with an input impedance of 10kΩ, enabling connection to sensors such as pressure transducers, speed encoders, and temperature transmitters for accurate data collection. AO channels output 0-10V DC or 4-20mA DC signals with an output impedance ≤500Ω, transmitting key motor operating parameters like speed, torque, and current to recorders or PLCs for real-time system monitoring.

Additional dedicated interfaces enhance its control flexibility: it includes 1 incremental encoder interface (HTL/TTL compatible, maximum 100kHz frequency) for motor speed feedback and closed-loop control, 1 pulse sequence input interface (0-10kHz) for external pulse-based frequency setting, and 2 relay output interfaces (250V AC/5A) for high-voltage device control and interlocking. For signal processing precision, it uses a 12-bit ADC converter for analog inputs, delivering ±0.1% full-scale sampling accuracy and a temperature drift ≤50ppm/C over -10 degrees Celsius to 60 degrees Celsius, ensuring signal collection error ≤±0.5% to meet precision control requirements for heavy-duty industrial equipment.
