Information About KL6021
The KL6021 is part of Beckhoff’s modular Bus Terminal system, enabling serial communication between automation devices and field components via RS422 or RS485 protocols. It supports both full and half-duplex operation, providing flexibility for connecting sensors, controllers, or communication devices across long distances. The module transmits differential signals with a line impedance of 120 Ω, ensuring stable operation and superior resistance to electromagnetic interference. Featuring electrical isolation between the K-bus and signal voltage, the KL6021 enhances system safety and data reliability. Configuration is handled directly through the Bus Coupler or the control software, eliminating the need for manual address settings.
Key Features:
- Versatile Serial Interface: Supports RS422 and RS485 communication standards for diverse industrial device integration.
- Full/Half Duplex Capability: Enables flexible communication modes to suit different network configurations.
- High Noise Immunity: Differential signaling and 120 Ω line impedance ensure stable data transmission in noisy environments.
- Long-Distance Communication: Allows transmission over twisted-pair cables up to 1000 meters in length.
- Buffered Data Handling: Features 128-byte receive and 16-byte transmit buffers for efficient data management.
- Electrical Isolation: Provides 500 V isolation between K-bus and signal voltage for enhanced protection.
- Automatic Configuration: Easily configured via Bus Coupler or controller without manual address setting.
- Compact Industrial Design: IP20-rated terminal ideal for DIN-rail mounting in control cabinets.
The KL6021 delivers the reliability and precision required for secure and stable serial data communication within distributed automation systems.
