ABB RDIO-01 Digital I/O Expansion Module  

1. Key Parameters

• Product Model: RDIO-01
• Product Series: ABB RDI-Series Industrial Digital I/O Expansion Modules (Automation System I/O Extension)
• Core Function: 16 digital inputs (DI) + 16 digital outputs (DO); PNP/NPN selectable (DI); DIN rail mounting; overload protection; compatible with ABB AC800M/800xA.

2. Core Features

• High Expansion Capacity: 32 total digital I/O channels (16DI+16DO) effectively expands the I/O port count of ABB main controllers, reducing the need for additional main modules.
• Flexible Input Adaptation: PNP/NPN selectable DI supports diverse field sensors (e.g., photoelectric sensors, limit switches), adapting to different wiring schemes.
• ABB System Compatibility: Plug-and-play integration with AC800M/800xA—no custom firmware, enabling quick deployment in existing systems.
• Industrial Durability: -25℃~+60℃ operating range, 500Vrms isolation, and DO overload protection withstand electrical noise, vibration, and harsh industrial conditions.

3. Application Fields

• Manufacturing Lines: Connects photoelectric sensors (DI) and conveyor actuators (DO) to AC800M PLCs in automotive/electronics assembly lines.
• Process Control: Links limit switches (DI) and solenoid valves (DO) to 800xA DCS in chemical/pharmaceutical reactor control systems.
• Utilities: Expands I/O ports for water pump status monitoring (DI) and valve control (DO) in municipal water treatment plants.

4. Precautions

• Compatibility: Use exclusively with ABB AC800M/800xA systems; avoid matching with non-ABB controllers to prevent communication failures.
• Installation: Separate I/O wiring from high-power cables (>10A) to reduce EMI; torque terminal screws to 0.5~0.7 N·m; confirm DI type (PNP/NPN) matches sensors.
• Maintenance: Check DI/DO channel responsiveness quarterly; clean terminals monthly (remove dust); replace if overload protection triggers frequently.
• Spare Parts: Use genuine ABB RDIO-01 units—non-genuine modules may cause I/O signal loss or incorrect actuator control.
