Beckhoff PLC module KL2424

The Beckhoff KL2424 is a 4-channel digital output terminal designed to interface 24 V DC control signals with actuators, providing electrical isolation between the control and field levels. 

Key Features:

• Output Channels: Four independent channels, each capable of handling up to 2 A of current.
• Signal Indicators: Each channel is equipped with an LED to display its signal state, facilitating easy monitoring.
• Connection Technology: Supports 2-wire connections, allowing direct interfacing with actuators.
• Overload Protection: Features short-circuit protection with a short-circuit current of less than 70 A and breaking energy of less than 1.7 J per channel.
• Reverse Voltage Protection: Incorporates safeguards against reverse polarity to prevent potential damage.
• Electrical Isolation: Offers 500 V isolation between the K-bus and field potential, ensuring system safety.

Specifications:

• Nominal Voltage: 24 V DC (-15%/+20%).
• Load Types: Suitable for ohmic, inductive, and lamp loads.
• Current Consumption:
  • Power Contacts: Typically 30 mA plus the load.
  • K-bus: Approximately 9 mA.
• Operating Temperature Range: -25°C to +60°C.
• Protection Rating: IP20, indicating suitability for indoor environments.

Applications:

The KL2424 is ideal for applications requiring reliable digital signal interfacing, such as:

• Industrial Automation: Controlling actuators like solenoids, relays, and motors.
• Building Automation: Managing lighting systems, HVAC controls, and security mechanisms.
• Process Control Systems: Interfacing with various field devices to ensure precise process management.
