B&R X20CP3686X

1. Overview

2. Key Specifications

3. Product Features

• Modular Design: Additional I/O, communication or functional modules can be integrated via the X20 system’s Hub expansion slots, enabling highly customized configurations.
• High Real-time Performance: Equipped with a built-in POWERLINK V2 interface and supporting Poll-Response-Chaining (PRC) mode, it meets stringent real-time control requirements.
• Multi-interface Integration: Integrates RS232, Ethernet, USB, POWERLINK and X2X Link in one unit, simplifying wiring and enhancing system reliability.
• Robust and Durable: Compliant with IP20 industrial protection standards, featuring a wide operating temperature range and voltage tolerance, making it ideal for harsh field conditions.
• Easy Maintenance: The modular structure, standardized plug-and-play interfaces and unified diagnostic LEDs facilitate quick on-site detection and module replacement.

4. Structure and Components

• Control Unit (CPU + Memory + Storage)
• Power Module (24 V DC input, internal voltage regulation)
• Communication Interface Board (Ethernet, POWERLINK, RS232, USB, X2X Link)
• Expansion Slots (3 slots for inserting X20 I/O, fieldbus or functional modules)
• Housing (Metal casing providing mechanical support and protection)

5. Typical Application Areas

• High-speed packaging and sorting systems
• Robot control and collaborative robot (cobot) master stations
• Machine tool numerical control (CNC) systems
• Complex assembly lines and flexible manufacturing cells
• Process control systems requiring high-speed Ethernet or POWERLINK real-time communication

6. Installation and Maintenance Guidelines

• Mounting Orientation: Supports both horizontal and vertical mounting. Ensure unobstructed heat dissipation channels when installed vertically.
• Environmental Requirements: Operating temperature ranges from -25 °C to 50 °C (vertical) or -25 °C to 55 °C (horizontal); relative humidity 5% – 95% (non-condensing); compliant with IP20 protection class.
• Power Connection: Use a 24 V DC power supply, ensuring the current does not exceed 1.5 A. The internal fuse is non-replaceable.
• Wiring and Cabling: Ethernet and POWERLINK use shielded RJ45 interfaces, with a maximum link length of 100 m.
• Module Replacement: Insert or remove expansion slot modules only when the power is off. The system will automatically detect the module and display its status via the diagnostic LEDs.
• Regular Inspection: It is recommended to inspect power terminals, interface connections and heat sink cleanliness every 6 months to ensure long-term reliable operation.
