Schneider BACnet/IP gateway SpaceLogic KNX BMS LSS100300 Bidirectional Linkage

Description: Schneider Electric’s SpaceLogic KNX BMS IP Gateway, model LSS100300, is a professional bidirectional multifunctional BACnet/IP gateway dedicated to integrating KNX installations with building automation system (BMS) devices. As a core integration component in commercial building automation scenarios, it features a dual main communication interface—KNX TP and IP—with full support for the BACnet protocol, enabling seamless data interaction and collaborative control between KNX systems and various building automation devices.

The device integrates three key components into one compact unit: a KNX IP router (supporting up to 500 objects), a KNX IP interface, and a DPSU choke power supply. This integrated design eliminates the need for separate IP routers and KNX power supplies (within specified parameters), simplifying the system architecture while significantly reducing deployment costs and time for professional installers. Configuration and commissioning are streamlined and efficient, thanks to the embedded application that simplifies complex setup processes, ensuring quick on-site deployment and debugging.

Tailored for commercial building installations, the gateway is BTL (BACnet Testing Laboratories) certified as an Application Specific Controller (B-ASC), guaranteeing 100% compatibility with all BACnet-compliant devices and enabling seamless integration into any BACnet-based building automation system. With a robust industrial-grade design, it maintains stable performance in commercial environments, adhering to strict environmental and safety standards. Backed by an 18-month contractual warranty, the product fully reflects Schneider’s expertise in building automation integration and commitment to reliable, cost-effective solutions for professional installers and building managers.
