ABB LDMUI-01 61320946C | I/O module

Product Name

Core Functions and Technical Positioning

1. Device Type and Technical Characteristics

• Multi-Functional I/O Integration: Combines analog input/output (AI/AO) and digital input/output (DI/DO) capabilities in a single module, supporting a variety of signal types (e.g., 0-10V, 4-20mA for analog; 24V DC for digital)
• High Precision and Fast Response: Achieves ±0.1% full-scale accuracy for analog signals and supports response times <2ms for analog I/O and <1ms for digital I/O.
• Wide Voltage Range: Operates on 24V DC power supply with built-in overvoltage and undervoltage protection
• Rugged Design: Features an IP67-rated enclosure, ensuring reliable performance in harsh industrial environments (-20°C to +70°C temperature range).

2. Core Functions

• Signal Conversion: Converts analog signals from sensors (e.g., temperature, pressure) into digital data for controller processing and vice versa.
• Control Execution: Drives actuators (e.g., valves, relays) based on control commands, enabling real-time adjustments in industrial processes1824.
• Protocol Support: Integrates with industrial communication protocols like Modbus RTU and PROFIBUS, facilitating seamless integration with PLCs and SCADA systems
