WEINZIERL KNX IO 532.1 secure Compact Dimming and Switching Actuator

Description

Introduction

The WEINZIERL KNX IO 532.1 secure (Art.-Nr. 5503) is a compact, combined dimming and switching actuator designed for modern KNX building automation systems. Occupying a single DIN rail width (1 module or 18 mm) and weighing approximately 60 g, this unit combines one PWM dimming output for 12..24 V DC LEDs with one 230 V AC / 8 A bistable relay output. Powered directly via the KNX TP bus line, it provides essential control capabilities without consuming excess panel space. This device is part of our KNX Actuators range.

In addition to basic output management, the KNX IO 532.1 secure features 16 independent logic and timer functions and fully supports KNX Data Security. The device enables direct control via ETS without requiring an upfront download, simplifying testing and installation. Given the specific load parameters and compact nature, consultants and procurement teams should verify exact model specifications, EAN codes, and project BOQs against official WEINZIERL documentation prior to ordering.

Key Features

• 1 PWM dimming output channel (12..24 V DC, max. 6 A load current, 600 Hz frequency).
• 1 bistable relay output channel (230 V AC / 8 A switching capacity).
• KNX TP Bus powered with System B KNX device model implementation.
• Supports KNX Data Security for encrypted network communication.
• 16 independent internal logic and timer control functions.
• Supports ETS direct control without requiring full application download during setup.
• Local user interface with 2 buttons, 3 multicolor LEDs, and red KNX programming LED.
• Pluggable 3-pole screw connectors for dimming and switching field wiring.

Benefits

• Space-Efficient 1-Module Housing: Combines dimming and switching channels into a single 18 mm DIN rail width to optimize distribution enclosure density.
• KNX Data Security: Supports official KNX Data Security protocols to protect automation networks against unauthorized access and signal tampering.
• Dual Output Versatility: Includes a 600 Hz PWM channel (12..24 V DC, up to 6 A) for LED strips/panels and a bistable relay channel (230 V AC / 8 A) for general switching.
• Integrated Logic Features: Incorporates 16 independent functions for custom logic operations and timer controls without requiring external logic modules.
• Efficient Diagnostics: Built-in local interface with 2 push buttons and 3 multicolor LEDs enables immediate manual state visualization and local testing.
• Flexible Commissioning: Supports ETS direct control capabilities alongside compatibility with ETS 4.2 (or higher), ETS 5, and ETS 6.

Applications

• Constant-Voltage LED Dimming: Suitable for controlling 12 V or 24 V LED panels and strips using PWM dimming controls.
• Versatile Load Control: Drives standard 230 V switching circuits, scene controls, or PWM control for thermoelectric heating valve drives.
• High-Density Panel Installations: Designed for space-constrained residential or commercial distribution boards requiring combined switching and dimming.

Installation Notes

• Mounting & Terminal Wiring: Install on standard 35 mm DIN rails (18 mm width). Connect the KNX bus terminal (red/black) and wire load circuits using the pluggable 3-pole screw connectors.
• Load Constraints: Note that the bistable relay capacity (230 V AC / 8 A) may decrease significantly depending on whether the connected load is capacitive or inductive.
• Procurement Verification: Cross-reference Art.-Nr. 5503 and EAN 4260262775030 with official datasheets to ensure correct model selection and avoid wrong orders.

Developer Resources

• Official product database files available for ETS 4.2, ETS 5, and ETS 6.
• Technical datasheet, user manual, CE declaration, and CAD/3D models available via WEINZIERL official documentation.
