KL3062 | BECKHOFF | Bornier de bus

Description

Processing analog input signals in the 0 to 10 V range, the BECKHOFF KL3062 Bus Terminal features two single-ended channels designed for direct connection to industrial sensors and transmitters. This compact input module converts analog physical values into digital signals with a 12-bit resolution, ensuring reliable signal transmission to the higher-level automation controller via the K-bus. Utilizing a common internal ground connection for both channels, the terminal minimizes wiring complexity in standard control cabinet installations.

The KL3062 provides comprehensive galvanic isolation up to 500 V between the input circuitry and the internal K-bus. Operating without the need for dedicated power contacts, the terminal derives its required operating power directly from the K-bus interface. The robust IP20 design and standard DIN rail mounting compatibility make it suitable for seamless integration in complex PLC and DCS architectures.

Installation Guidelines

• Mounting: Snap the module directly onto a standard 35 mm DIN rail (EN 60715). Ensure the locking mechanism engages securely.
• Wiring: Use appropriate wire sizes with terminal connectors. For solid or stranded wires, ensure the maximum cross-section conforms to the terminal blocks' limit.
• Shielding: Connect the analog cable shields to terminal points 4 or 8 to prevent electrostatic and electromagnetic interference from disrupting signal integrity.
• Grounding: Ensure the DIN rail is grounded to a low-impedance earth system in compliance with standard electrical installation codes.

Compliance and Certifications
