Information About KL4034
The KL4034 is part of Beckhoff’s modular K-bus terminal system, designed for generating analog voltage outputs in control and automation applications. With four single-ended channels and ±10 V output range, it provides precise signal generation for actuators, drives, and control elements. The terminal connects directly to the K-bus, which supplies both communication and power, eliminating the need for separate wiring. Its 12-bit resolution and electrical isolation ensure accurate and interference-free analog signal transmission. The KL4034 automatically integrates into the process image of the connected Bus Coupler or controller, simplifying configuration and operation.
Key Features:
- Four Analog Outputs: Provides four voltage outputs for control of analog devices or signal generation in automation systems.
- High Accuracy: Offers 12-bit resolution and ±0.1% output error for precise voltage control.
- Wide Voltage Range: Delivers ±10 V signal levels suitable for most industrial analog control inputs.
- Electrically Isolated Design: 500 V isolation between K-bus and output channels ensures protection and signal integrity.
- Simple Integration: Requires no address or configuration setup, automatically recognized by the Bus Coupler.
- Fast Response: Achieves a conversion time of approximately 2 ms for dynamic analog signal output.
- LED Status Indication: RUN LEDs provide immediate visual feedback of communication and channel activity.
- Compact and Durable: IP20-rated housing suitable for DIN-rail installation within industrial control panels.
The KL4034 delivers the reliability and precision required for analog control, voltage signal output, and smooth integration into Beckhoff automation systems.
