EAE KMG103 KNX/Modbus Gateway (SMP-KMG103-220V-640ma)

Description

Introduction

The EAE KMG103 KNX/Modbus Gateway (Order Code: SMP-KMG103-220V-640ma) provides an efficient, cost-effective solution for modern room automation topologies. Designed to directly bridge a KNX line with a Modbus TCP line, the unit eliminates the need to deploy dedicated IP routers for every individual room in a project. This direct interface simplifies infrastructure engineering while maintaining high-speed communication between room control systems and central management platforms. This device is part of our KNX System Components range.

Equipped with an internal power supply option (320mA or 640mA), the KMG103 removes the requirement for an auxiliary KNX power supply unit in each room installation. It also incorporates 2 dry contact inputs for door and window monitoring, along with integrated advanced logic functions that automate room guest scenarios—such as pre-welcome, welcome, leave, and check-out—without relying on traditional cardholder energy savers.

Key Features

• – Direct gateway functionality bridging a local KNX line and a Modbus TCP line.
• – In-built power supply delivering 320mA or 640mA output.
• – 2 dry contact inputs dedicated to door and window contact status monitoring.
• – Integrated logic engine for automated occupancy scenarios (pre-welcome, welcome, leave, check-out).
• – Compatible with ETS5 and ETS6 engineering software tools.
• – Supports up to 4 simultaneous KNXnet/IP Tunnelling connections.
• – Designed for integration with GRMS software, hotel PMS, and leading door lock brands.

Benefits

• – Integrated Architecture Savings: Bridges KNX lines directly to Modbus TCP networks, saving cost by removing the necessity for additional per-room IP Routers.
• – Reduced Hardware Footprint: The in-built power supply option (320mA or 640mA) eliminates the need for a separate room KNX power supply, simplifying board layout.
• – Energy Optimization Without Cardholders: Onboard logic functions execute pre-welcome, welcome, leave, and check-out automated scenarios based on room occupancy data, driving energy savings without physical keycard readers.
• – Comprehensive System Integration: Seamlessly connects with GRMS software, hotel PMS platforms, and leading door lock access systems.
• – Multi-Session Tunnelling: Supports up to 4 simultaneous KNXnet/IP tunnelling connections for simultaneous ETS engineering and Group Monitor monitoring.
