Beckhoff KS6011 KS Series Bus Terminal

Description

Serial data transmission via 20 mA current loop interfaces is facilitated by the Beckhoff KS6011 Bus Terminal. This module enables the direct integration of active or passive TTY-interface devices into the Beckhoff K-bus system, bypassing the need for external converters. Operating as a full duplex interface on two channels (TxD and RxD), the device handles communication tasks independently of the higher-level bus system, utilizing internal data buffers to ensure reliable data transfer even during intensive process cycles.

The unit features a pluggable wiring design typical of the KS series, which simplifies installation, commissioning, and maintenance. Wiring connection blocks can be detached as a single unit without disconnecting individual conductors, reducing downtime during module replacement. Complete galvanic isolation provides high-noise immunity, making it suitable for long-distance point-to-point connections in challenging industrial environments.

Features

• Active/passive 2 x 20 mA current loop (TTY) interface technology.
• Full duplex data transfer across dedicated transmit (TxD) and receive (RxD) channels.
• Configurable transfer rates ranging from 1200 to 19,200 baud (default: 9600 baud).
• Integrated data buffers including a 128-byte receive buffer and a 16-byte transmit buffer.
• Pluggable wiring level for rapid tool-free maintenance.
• Galvanic isolation of 500 V between the K-bus backplane and signal lines.
• Flexible process image configuration via standard Bus Couplers or controllers.

Applications

• Connection of legacy terminal systems, printers, and laboratory instruments with TTY ports.
• Long-range point-to-point serial communication (up to 1000 m) in high-noise manufacturing plants.
• Industrial weighing systems and barcode reader integration.
• Hazardous area automation applications requiring Ex nA certified components.

Technical Specifications

Installation Guidelines

• Mount the unit on standard 35 mm DIN rails complying with EN 60715. Ensure the interlocking double slot and key system is secure.
• Ensure the pluggable wiring connector is fully locked into place before applying power to the K-bus backplane.
• To optimize noise immunity over long transmission distances (up to 1000 m), use high-quality shielded twisted pair cables.
• Maintain clear ventilation spacing in accordance with the system manual's environmental specifications.
