Beckhoff KS9560 Power Supply Terminal 24 V DC/24 V DC

Product Overview

The Beckhoff KS9560 (KS9560) is a specialized power supply terminal designed for the K-bus system, providing electrical isolation and voltage regulation within industrial automation networks. Operating as a 24 V DC to 24 V DC converter, this terminal ensures stable power delivery to sensitive downstream field components. By providing galvanic isolation, it prevents ground loops and electrical interference, which is critical for maintaining signal integrity and reducing unplanned downtime in PLC-controlled machinery and distributed I/O systems.

Technical Configuration

The KS9560 features a robust design optimized for the modular Beckhoff Bus Terminal series. Its hardware architecture includes automatic short-circuit protection with an automatic restart capability, enhancing system resilience against field wiring faults. The terminal is housed in a compact polycarbonate terminal housing with a pluggable wiring level, allowing for rapid field replacement without disturbing permanent wiring. It is engineered to withstand demanding environmental conditions, meeting strict EMC, shock, and vibration standards (EN 60068 and EN 61000), and holds global certifications including CE, UL, and ATEX for hazardous area operation.

FAQs

What is the benefit of the electrical isolation provided by this terminal?

The electrical isolation (500 V AC) effectively decouples the field side from the control side. This protects your PLC and communication modules from voltage spikes or short circuits that may occur on the field-side wiring, significantly increasing system reliability.

How does the automatic restart feature function?

In the event of an output short-circuit, the KS9560 immediately limits the current to approximately 0.15 A. Once the fault is removed from the field side, the terminal automatically attempts to restore the 24 V DC output without requiring a manual reset or power cycle of the entire system.

Is this terminal suitable for hazardous locations?

Yes, the KS9560 carries the ATEX Ex nA IIC T4 Gc marking, permitting its use in specific explosive atmospheres (Zone 2), provided it is installed within an appropriate protective enclosure.

Can I mount this terminal alongside standard high-current terminals?

Yes, the KS9560 supports side-by-side mounting using the integrated double slot and key connection system. However, ensure that the current load on the power contacts does not exceed the Imax of 10 A for the entire terminal block assembly.

Installation Guidelines and Best Practices

• Wiring Technique: The KS9560 uses spring-actuated connections. Use a standard screwdriver to actuate the spring before inserting the wire (0.08–1.5 mm²). Ensure the stripping length is exactly 9–10 mm to maintain proper contact pressure and prevent exposed conductors.
• Thermal Management: Although the terminal is rated for operation up to 55 deg C, mounting it in a dense terminal block configuration can lead to localized heat buildup. Ensure adequate spacing or forced-air cooling if the surrounding terminal blocks are also operating near their maximum current ratings.
• Grounding: Always connect the terminal to a high-quality, low-impedance ground path to ensure the EMC immunity and emission ratings (EN 61000-6-2/4) are maintained throughout the life of the installation.
• Mechanical Installation: The terminal is designed for 35 mm DIN rail mounting. Use the integrated lock to ensure the terminal is firmly fixed, especially in high-vibration applications like robotics or heavy conveying machinery.
