CX2042-N031-0004 | BECKHOFF | Module CPU de base

Description

The CX2042-N031-0004 is a specialized Basic CPU Module component for the Beckhoff CX2000 series embedded PCs. This specific variant is equipped with a high-speed RS422 interface provided via a 9-pin D-sub socket. It is factory-configured as a full-duplex endpoint with active termination enabled, making it suitable for high-integrity point-to-point serial communication in demanding industrial control environments where signal reflection must be minimized.

Technical Specifications

Key Considerations

• Interface Standard: The RS422 interface offers high immunity to electrical noise and is capable of supporting longer cable runs compared to RS232, which is ideal for communication between the Embedded PC and remote industrial devices (such as drives, sensors, or HMI units).
• Duplexing: By operating in full-duplex mode, the module allows for simultaneous transmission and reception of data, increasing the effective throughput for control tasks.
• Termination: The built-in termination ensures that the serial line is properly matched to the characteristic impedance of the cable, which is critical for preventing signal degradation in high-speed or long-distance communication setups.
• Integration: As part of the CX2000 modular series, this module is designed for seamless integration with other system components, including power supply units and various I/O modules, maintaining the compact footprint of the Embedded PC system.
