Compact Control Hub for Seamless AV Automation 

Empower your AV environments with the Kramer SL-240C, a versatile master/room controller that automates devices via Ethernet, featuring four bidirectional RS-232 ports, four IR emitters, four GPI/O interfaces, and four relay controls for managing displays, audio, lighting, and sensors. Its high-performance architecture supports scalable programming with Kramer Control software and API, plus resilient PoE powering and LED indicators for easy status monitoring. Ideal for commercial, educational, and government spaces, it enables centralised, error-free automation to streamline operations and enhance user experiences.

  • SL−240C is a compact master/space controller (Kramer Control brain) with PoE. It can operate over Ethernet with control interfaces that include: four bidirectional RS−232, four IR, four GPI/O, and four relays. It controls devices such as scalers, video displays, audio amplifiers, Blu−ray players, sensors, screens, shades, door locks, and lights. Multiple Kramer Ethernet control gateways can be used to add remote I/O ports.

    • Space Controller — Controls any AV device/display with its corresponding logic.

    • High Performance Architecture — Enables a scalable and flexible programming platform.

    • 4 RS–232 Bidirectional Control Ports — For controlling devices via bi–directional serial control protocols.

    • 4 IR Emitter & 1 IR Receiver Control Ports — Control devices via IR control protocols and learn commands from IR remotes.

    • 4 GPI/O Control Ports — Control devices via general purpose I/O ports, program configured as digital input, digital output or analog input interface for controlling sensors, door locks, audio volume and lighting control devices.

    • 4 Relay Control Ports — Control devices via relay contact closure, such as opening and closing drapes, shades, blinds, and projection screen scrolling.

    • Resilient powering with PoE and optional PSU (not included).

    • Network Support — 10/100/1000Mbps Ethernet, 802.1x authentication.

    • LED Indicators — I/O port state and system status.
