BECKHOFF KS9515 Power Supply Terminal 15 V DC

Product Overview

The KS9515 (KS9515) Power Supply Terminal converts a standard 24 VDC input voltage into a highly stable, regulated 15 VDC output voltage. Engineered for industrial automation networks, manufacturing plants, and process environments, this module steps down power safely to drive specific field devices and specialized analog bus terminals, such as the KS4021. By delivering clean, low-ripple power directly on the DIN rail, the module isolates sensitive downstream instrumentation from heavy system noise, mitigating unexpected hardware faults and minimizing facility downtime. It utilizes a pluggable wiring level characteristic of the Beckhoff KS series, enabling seamless maintenance and component swaps without requiring wire-by-wire terminal reconstruction.

Technical Configuration

The KS9515 features an internal DC-DC converter block designed to handle input variations ranging from -15% to +20%. It outputs a precise 15 VDC (+/-1%) up to a maximum current capacity of 0.5 A. An integrated overcurrent LED provides real-time visual diagnostics directly on the front panel, alerting field technicians to overload states immediately.

The hardware architecture incorporates full short-circuit protection and a residual ripple profile restricted to less than 5 mV, making it an ideal choice for high-precision sensor loops. The terminal housing features a standard 12 mm width with a double slot and key system, allowing interlocking, side-by-side integration alongside standard K-bus communication modules.

Technical Specifications

Product FAQs

How does the overcurrent LED assist in field troubleshooting?

The integrated overcurrent LED illuminates when the load connected to the 15 VDC output exceeds the 0.5 A design limit or if a direct short-circuit occurs. The module limits the output current safely until the fault condition is cleared, preventing thermal damage to the terminal or adjacent K-bus modules.

Can the KS9515 supply power to multiple analog modules simultaneously?

Yes, provided the cumulative current consumption of all connected field instruments and terminals stays below the 0.5 A maximum rating. Always verify the individual technical documentation of downstream modules to calculate the total current budget.

Is it possible to use this power supply module on a standard KL-series setup?

The KS9515 features a pluggable wiring housing, but it maintains standard K-bus dimensions and internal backplane connections. It can sit side-by-side with KL-series terminals, though it uses the detachable plug level specific to the KS design family.

Engineering Deployment and Safety Manual

• Terminal Termination Procedure: Use a dedicated flat-head screwdriver to open the spring-actuated tension clamps. Strip all solid (e), stranded (st), or ferrule-terminated (f) conductors to a length of 9 to 10 mm. Acceptable conductor sizes range from AWG 28 to 16 for solid/stranded wires, and AWG 26 to 16 for lines utilizing a ferrule.

• Mechanical Rail Installation: Mount the module vertically on a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking mechanism engages securely with an audible click. Slide the terminal laterally to mate the double slot and key connection with neighboring units, ensuring solid mechanical stabilization under high-vibration conditions.

• Explosion Protection Protocol: This device is rated II 3 G Ex nA IIC T4 Gc for Zone 2 application. The terminal must be housed within an IP54 rated control enclosure to satisfy local safety standards. Never actuate or disconnect the pluggable wiring assembly while the input power circuit is active.
