KL2641 | BECKHOFF | Bus Terminal Relay Output Module

Description

The KL2641 is a high-performance Bus Terminal from Beckhoff featuring a 1-channel relay output designed for heavy-duty switching applications. This module incorporates a bistable relay contact, which retains its state without continuous power consumption for the coil, providing significant energy efficiency and reliability. The terminal is equipped with manual operation capabilities, allowing for direct override of the relay contact, and includes two inputs for monitoring manual and automatic status. It is engineered to handle up to 16 A switching current, making it ideal for controlling ohmic, inductive, and lamp loads in industrial automation systems.

Features

• 1-channel relay output (make contact)
• High switching capacity up to 5 kVA
• Integrated manual operation switch for testing and override
• Bistable relay contact design for reduced power consumption
• Status monitoring for manual and automatic operation states
• Robust contact material (AgSnO2) for extended durability

Installation Guidelines

• Mounting: The KL2641 is designed for integration into standard DIN rail assemblies. Ensure the module is securely locked into place.
• Wiring: Given the high current capacity (16 A), ensure all wiring uses appropriate gauge cables to prevent overheating. Follow local electrical safety codes for 230 V AC / 440 V AC circuits.
• Manual Override: Use the manual operation feature cautiously during system maintenance to avoid unexpected equipment activation.
• Environmental: The unit is IP20 rated. It must be installed in a protected control cabinet to prevent exposure to conductive dust, moisture, or extreme environments.
