WEINZIERL KNX IO 520.1 secure Shutter Actuator

Description

Introduction

The WEINZIERL KNX IO 520.1 secure (Art.-Nr. 5515) is an ultra-compact, 1-module (18 mm) DIN rail KNX TP shutter actuator engineered for precise control of blinds, shutters, or motorized window drives. Operating on KNX System B and fully compatible with ETS 5 or higher (including ETS 6), this high-density device integrates a single blind output channel with electrically interlocked relay contacts rated for 230 V~ / 8 A (inductive load 3.5 A at cosΦ = 0.4). This device is part of our KNX Actuators products range.

Equipped with two multi-voltage binary inputs (12 to 230 V AC/DC), the device allows conventional external switches to directly operate the shutter output in its unconfigured factory state. Once commissioned via ETS software, the binary inputs function independently across the KNX network while granting access to 16 embedded logic, timer, comparison, and calculation functions. The module also features native KNX Data Security and supports direct ETS control without downloading.

Key Features

• 1-channel blind/shutter output with electrically interlocked relay contacts (230 V~ / 8 A resistive, 3.5 A inductive).
• 2 binary input channels accepting external voltages from 12 to 230 V AC/DC with < 1 mA input current.
• Compact 18 mm plastic DIN rail housing (1 module width) weighing approximately 65 g.
• Native KNX Data Security support and compatibility with ETS 5 (or higher) and ETS 6.
• KNX TP bus powered with low current consumption and System B device model.
• User interface featuring 2 operation buttons, 3 multicolor LEDs, and a red KNX programming LED.
• Pluggable 3-pole screw connectors for blind output and dual binary inputs.

Benefits

• Space-Saving Form Factor: Requires only 1 DIN rail module (18 mm width) and weighs approximately 65 g, maximizing cabinet density.
• Robust Security Standard: Integrated KNX Data Security prevents unauthorized bus access and tampering in modern smart installations.
• Flexible Binary Inputs: Supports wide-range signal input voltages from 12 to 230 V AC/DC for seamless integration of legacy switches.
• Pre-Configured Direct Control: Pre-set factory logic links binary inputs directly to the actuator output before ETS commissioning.
• Integrated Logic Suite: Features 16 independent logic, timer, comparison, and calculation functions to minimize separate logic module requirements.
• Efficient Setup & Testing: Enables direct control through ETS without code downloads, supplemented by local push buttons and multicolor status LEDs.

Applications

• Motorized Shutter & Blind Automation: Controls directional up/down movement and slat position for single motorized blinds or shutters.
• Window Drive Control: Interlocked switching protection for automated 230 V motorized window actuators.
• Conventional Switch Integration: Interfaces external 12–230 V pushbuttons and switches directly into a secure KNX network.

Installation Notes

• Mounting & Terminal Wiring: Snap onto standard 35 mm DIN rails (1 module width). Connect the KNX TP bus using the red/black terminal block and connect high-voltage output and signal inputs via the pluggable 3-pole screw terminals.
• Electrical Parameters: Strictly adhere to the relay load limits (230 V~ / 8 A resistive, 3.5 A inductive) and ensure input voltages remain within the 12 to 230 V range.
• Procurement & Commissioning: Verify exact model data (WEINZIERL Art.-Nr. 5515, EAN 4260262775153) against project BOQ requirements before performing ETS 5/6 assignment and KNX Data Security key entry.

FAQ

What is the maximum electrical rating for the blind output relay?

The blind output relay supports 230 V~ with a resistive load up to 8 A and an inductive load (cosΦ = 0.4) up to 3.5 A. Explore more WEINZIERL KNX solutions for professional building automation projects.

Which signal voltages are compatible with the binary inputs?

The two binary inputs accept external switch signals ranging from 12 to 230 V AC/DC with input currents under 1 mA. For certificates and current technical files, refer to the official WEINZIERL product page.

How do the binary inputs operate out of the box?

In their unconfigured state, the binary inputs directly drive the local shutter actuator channel. Upon ETS commissioning, they can be unlinked and assigned independently.

Which ETS versions support the WEINZIERL KNX IO 520.1 secure?

The device is compatible with ETS 5 (or higher) and ETS 6, fully supporting KNX Data Security and direct manual control.

What is the exact product model?

The order/model code for this page is KNX IO 520.1 secure. Match it against project documents before purchase.

Who is the manufacturer?

This product is manufactured by WEINZIERL.
