Product Description:
The KL2808 is an 8-channel Digital output terminal manufactured by Beckhoff that is used for switching binary control signals to actuators in industrial automation. The digital output terminal supports a rated load voltage of 24 V DC and provides reliable output switching for a variety of load types.
The KL2808 digital output terminal delivers a maximum output current of 0.5 A per channel and is protected against short circuits and polarity reversal. The terminal is designed for 2-wire connection technology and offers eight digital outputs, each with a dedicated LED indicator that shows the signal state. Each channel has an energy barrier of less than 150 mJ, and the 500 V field potential or K-bus is electrically insulated from the outputs. A 35 mm DIN rail is suitable for mounting the terminal in accordance with EN 60715 regulations. Various switching tasks can be accomplished with the help of the output terminal, which supports ohmic, inductive, and light loads. Normally, using 20 mA from the K-bus, the output terminal in the process image has a bit width of 8 bits. Supporting versatile integration is the durable mounting mechanism and the variable installation location.
The KL2808 output terminal has features that enhance operational safety and flexibility. The short-circuit proof outputs ensure reliable operation, while electrical isolation protects both control and field sides. The 2-wire connection simplifies wiring and maintenance. The product’s compatibility with different load types allows for versatile use in industrial automation. The presence of LED indicators for each output helps in quick diagnostics. The output terminal is designed to maintain performance and safety standards, supported by multiple international approvals and compliance with relevant EMC and vibration standards.
Frequently Asked Questions about KL2808:
Q: Does KL2808 provide short-circuit protection for outputs?
A: Yes, digital output terminal outputs are short-circuit proof, that helps protect the device and connected loads from damage during faults.
Q: Why is electrical isolation important in KL2808?
A: Electrical isolation at 500 V separates the K-bus from the field potential that enhances safety and prevents interference between control and field circuits.
Q: How does KL2808 indicate output signal states?
A: The digital output terminal uses dedicated LED indicators for each output that provide immediate visual feedback on the signal status for diagnostics and monitoring.
Q: Do KL2808 terminals support variable installation positions?
A: Yes, a digital output terminal can be installed in any position that allows flexible integration into different control cabinets and panel layouts.
Q: Why does KL2808 use 2-wire connection technology?
A: 2-wire connection technology in digital output terminal simplifies wiring that reduces installation time and potential wiring errors in automation systems.
