BECKHOFF KL2828 Digital Output Terminal

The KL2828 is an 8-channel digital output terminal manufactured by BECKHOFF, designed for switching 24 V DC actuators in industrial control applications. This Bus Terminal module provides high-density output control, capable of driving ohmic, inductive, or capacitive loads with a maximum current of 2 A per channel, totaling up to 10 A for the entire module. Engineered for durability, the KL2828 includes robust short-circuit protection and reverse voltage protection, ensuring reliable performance in demanding automation environments.

Features

• 8 digital output channels with 2-wire connection technology
• Supports ohmic, inductive, and capacitive load types
• High load capacity: 2 A per channel (10 A total sum current)
• Integrated short-circuit protection and reverse voltage protection
• Electrical isolation of 500 V between K-bus and field potential
• Compact design for vertical installation
• Plug-and-play operation; no address or configuration settings required

Applications

• Distributed I/O systems for factory automation
• High-density actuator control (solenoids, contactors, pilot lamps)
• Machine and process control signaling
• Industrial control panels with space constraints

Technical Specifications

Installation Guidelines

• The terminal is designed for vertical installation on a standard 35 mm DIN rail.
• Ensure that the total current draw does not exceed 10 A across all 8 channels simultaneously.
• Use 2-wire connection technology to interface actuators directly with the module.
• Maintain ambient conditions between -25 and +60 degC to ensure operational longevity.
• Observe standard EMC guidelines (EN 61000-6-2/EN 61000-6-4) during cable routing and cabinet assembly to minimize interference.
