Description

Designed to stabilize supply voltages in highly dynamic drive systems, the **Beckhoff KS9570** buffer capacitor terminal provides reliable energy storage and overvoltage protection within the standard Bus Terminal system. This module absorbs regenerative energy generated during motor deceleration phases, protecting upstream power supplies and sensitive electronic components from overvoltage transients. Featuring a pluggable wiring level, the **KS9570 buffer capacitor** is fully compatible with all KSxxxx series Bus Terminals, allowing for rapid installation and simplified maintenance in demanding industrial environments.

Features

High-capacity 500 uF buffer for effective absorption of regenerative energy.
Integrated surge voltage protection threshold set above 56 V to safeguard field-side electronics.
Pluggable wiring level design for quick, tool-free terminal replacement without disconnecting field wiring.
Support for external braking resistor (recommended model ZB8110) with load-dependent 2-point control.
Robust electrical isolation of 1500 V between the K-bus and field potential.
Compact 12 mm housing width for optimized space utilization on standard DIN rails.

Applications

Dynamic motion control and servo drive systems.
Industrial manufacturing and packaging assembly lines.
Decentralized control cabinets requiring localized voltage stabilization.
Material handling systems with frequent start-stop and deceleration cycles.

Installation Guidelines

Mounting: Mount directly onto a standard 35 mm DIN rail conforming to EN 60715. Secure using the integrated locking mechanism.
Side-by-Side Installation: Align adjacent terminals using the double slot and key connection system to ensure proper mechanical stability and electrical contact.
Wiring: Use a suitable flat-head screwdriver to actuate the tension clamp spring. Insert stripped wire (9 to 10 mm stripping length) and release the spring to secure.
Ventilation: Ensure adequate clearance around the terminal housing to maintain operating temperatures within the specified 0 to +55 degC range.
