ABB UAC326AEV1 HIEE401481R1 Analog Digital I/O Card

Input Voltage: Three-phase 200 - 480VAC.

Output Current: 22A.

User Memory: 8MB.

I/O Memory: 0.98MB.

Operating Temperature: -25°C to +70°C.

Protection Class: IP40.

Supported Motion Axes: 100.

Communication Protocols: Supports multiple communication protocols for interconnection with other devices.

Integrated Drive Control: Houses all real-time logic and I/O needed to operate and protect a medium-voltage motor via the ACS800/ACS880 platform.

Flexible I/O: Mix of digital and analog channels that can be assigned to start/stop commands, speed reference inputs, alarm outputs, and process signals.

Multi-Protocol Networking: Simultaneous support for multiple fieldbus and Ethernet protocols allows seamless integration into diverse automation architectures.

Embedded Logic Capability: Built-in IEC 61131-3 runtime lets users implement custom sequencing, interlocks, and motor-protection routines without external PLCs.

Redundancy & Diagnostics: Dual-channel watchdog and relay outputs provide safe shutdown paths; onboard fault log stores the last 32 fault events with time stamps.

Parameter Management: Non-volatile memory holds up to 10 drive parameter sets for rapid changeovers between operating modes or different motor types.

Safety Functions: Supports integrated Safe Torque Off (STO) and optional Safe Stop 1/2 functions for compliance with SIL 2/PL d requirements.

HMI Integration: Compatible with ABB’s Drive Composer PC tool and optional keypad/display units for local monitoring, tuning, and firmware updates.

Integrated into the distributed energy coordination system, real-time acquisition of PV array voltage/current data via Ethernet/IP protocol, improving grid stability by 30%

Used for torque signal acquisition of welding robot clusters, coordinated with ABB IRC5 controller via Profinet protocol, achieving 0.05mm positioning accuracy, and processing more than 100,000 signals per day
