WEINZIERL KNX IP Router 751

Description

Introduction

The WEINZIERL KNX IP Router 751 (Art.-Nr. 5243) is a compact system device designed to function as a fast LAN backbone and programming interface within KNX building control networks. Enclosed in a space-saving housing measuring just 1 module (18 mm wide) for DIN rail mounting, it forwards telegrams between KNX TP lines over an Ethernet IP network, providing a highly reliable alternative to traditional KNX line couplers. This device is part of our KNX Gateway range.

Powered directly by the KNX TP bus line (consuming approximately 15 mA), this device eliminates the requirement for an auxiliary external power supply in distribution boards. System integrators and buyers should verify exact SKU details, part numbers, and bill of materials (BOQ) specifications against official manufacturer databases to ensure correct ordering and seamless network compatibility.

Key Features

• 1. Compact plastic housing for 35 mm DIN rail mounting (1 TE / 18 mm width).
• 2. Forwards telegrams between KNX TP and Ethernet IP (10BaseT LAN) networks.
• 3. Bus power consumption of approximately 15 mA via standard KNX connector.
• 4. Built-in RJ-45 connector for Ethernet LAN communication.
• 5. 5 KNXnet/IP Tunneling channels for programming and remote system access.
• 6. Controls include 2 diagnostic buttons and 1 dedicated KNX programming button.
• 7. Indicators include 3 bicolor status LEDs and 1 KNX programming LED.
• 8. Integrated 8 kByte filter table with support for Long Frame telegrams.

Benefits

• 1. Ultra-Compact 1 TE Form Factor: Requires only 18 mm of space on the DIN rail, optimizing panel capacity in crowded distribution enclosures.
• 2. Bus-Powered Operation: Operating power is drawn directly from the KNX bus line (approx. 15 mA), avoiding the need for an external power supply module.
• 3. Multi-Tunneling Support: Provides 5 simultaneous KNXnet/IP tunneling connections for concurrent access by programming tools and software.
• 4. Comprehensive ETS Support: Full support across multiple ETS generations, including ETS 3, ETS 4, ETS 5, and ETS 6.
• 5. Extended Filtering Capacity: Integrated 8 kByte filter table capable of managing up to 64k group addresses alongside Long Frame support.
• 6. On-Device Diagnostics: Features diagnostic buttons and multi-color status LEDs for fast local status verification and error diagnosis.

Applications

• 1. KNX TP Line Coupling via IP Backbone: Used to connect separate KNX TP lines across a LAN infrastructure as a high-speed IP backbone.
• 2. Bus Programming & System Interface: Serves as an Ethernet interface for commissioning, monitoring, and configuring KNX installations through ETS software.

Installation Notes

• 1. Mount the 1 TE plastic enclosure on a standard 35 mm DIN rail inside the distribution board.
• 2. Connect the physical KNX TP line using the standard bus terminal and attach the LAN cable to the RJ-45 Ethernet port.
• 3. Verify the product Art.-Nr. 5243 and EAN 4260262772435 against technical procurement documentation prior to site delivery to avoid wrong orders.
