Description

The BECKHOFF KS9528 is an AS-Interface power supply terminal designed for integration within the Beckhoff Bus Terminal system. The KS9528 generates a regulated 30 V DC output voltage from a 24 V DC input, delivering up to 1.25 A output current to supply AS-Interface components without requiring an external AS-Interface power supply unit. It features pluggable wiring, built-in short-circuit protection with automatic restart, and full isolation between the field level and the K-bus.

Features

Generates 30 V DC AS-Interface power directly from a 24 V DC input
Integrated short-circuit protection with automatic restart
Pluggable wiring design for convenient installation and replacement
High efficiency operation of approximately 95 %
Galvanic insulation of 1,500 V AC constant load between field level and K-bus
Standard 35 mm DIN rail mounting with double slot and key connection for side-by-side assembly

Applications

AS-Interface network power generation in PLC and control cabinets
Industrial automation systems utilizing Beckhoff Bus Terminal architectures
Distributed I/O configurations requiring localized 30 V DC AS-i field supply

Installation Guidelines

DIN Rail Mounting: Install on a standard 35 mm DIN rail conforming to EN 60715. Ensure the locking latch engages securely.
Side-by-Side Assembly: Interlock adjacent terminals using the double slot and key connection structure to maintain bus contact integrity.
Wiring: Actuate the spring clamps using a suitable screwdriver. Strip field wires to 8…9 mm before insertion into the pluggable terminal block.
Environmental Considerations: Ensure ambient operating temperatures remain between 0 degC and +55 degC in a non-condensing environment (max. 95 % RH). Ensure IP20 enclosure requirements are met inside a suitable control cabinet.
