Key Features and Technical Specifications

The RCU1212 is more than just a simple relay module; it’s a multi-faceted KNX device designed for easy integration. The unit is built for mounting on a DIN rail within a standard electrical cabinet, which simplifies the physical installation process. A significant advantage is that the RCU1212 is powered directly by the KNX bus and does not require an external power supply, further reducing wiring complexity and potential points of failure. The device’s robust design and extensive feature set are a testament to EAE Technology’s commitment to quality and innovation.

• Dual-Purpose Design: Outputs and Inputs: The RCU1212 is a standout product due to its dual functionality. It features 12 independent relay outputs, each rated at a robust 16A, for controlling a wide range of loads. In addition, it is equipped with 12 independent input channels, which can be configured as a universal interface for a variety of control functions. This combination of outputs and inputs in a single device is what makes the RCU1212 so versatile.
• Versatile Output Functions: The 12 outputs of the RCU1212 are grouped into three independent output channels, each of which can be configured for a specific operational mode. This flexibility is what sets the device apart and makes it suitable for diverse applications. The unit can be configured to act as:
  • Switching Outputs (x4): For simple on/off control of lights and other electrical loads.
  • AC Blind Control (x2): To manage AC-powered blinds and shutters with precise control.
  • DC Blind Control (x1): For controlling DC-powered blinds and shades.
  • 2-Point Valve Control (x2): To control two-pipe fan coil units for climate management.
  • 3-Point Valve Control (x1): To manage more complex three-pipe fan coil systems.
• Advanced Input Functionality: The 12 independent inputs of the RCU1212 transform it into a universal interface for the KNX bus. These inputs can be connected to standard push-buttons, switches, or dry contacts to perform a variety of functions, including:
  • Switch/Push-Button Input: To trigger lighting or other functions from a conventional wall switch.
  • Dimmer Control: To adjust light levels from a standard dimmer switch.
  • Shutter/Blinds Control: To manage blinds and shutters using a conventional input.
  • Scene Control: To recall pre-configured scenes with a single button press.
  • Value Transfer: To send specific values (e.g., temperature) from a sensor to the KNX bus.
  • Pulse Counter: To count pulses from a connected meter, useful for monitoring energy or water consumption.
• Integrated Logic and Advanced Features: The RCU1212 is not just a collection of inputs and outputs. It includes advanced internal logic and functions that enhance its operational intelligence. These features include:
  • Staircase Function: Automates lighting in stairwells for energy efficiency and convenience.
  • External and Internal Logic: Allows for complex, programmable automation scenarios based on conditions from other devices.
  • Priority and Threshold Functions: Enables assigning priority to certain commands and triggering actions when a pre-defined threshold is met (e.g., automatically turning off lights when a light sensor detects sufficient daylight).
  • Operating Hour and Sweep Functions: Useful for tracking device usage for maintenance purposes and for scheduling automated cleaning cycles.

Application Scenarios: Where the RCU1212 Excels

The all-in-one design and extensive functionality of the RCU1212 make it an ideal solution for a variety of applications, significantly reducing the number of individual devices required and simplifying the overall wiring scheme.

• Hotel Guest Rooms: In the hospitality industry, a seamless guest experience is paramount. The RCU1212 can serve as the central brain for a hotel room’s management system, managing everything from lighting scenes and blinds to the fan coil unit. By integrating with a Guest Room Management System (GRMS), it can activate “Welcome” scenes upon entry, automate climate control to save energy when a guest leaves, and manage “Do Not Disturb” notifications. This not only enhances guest satisfaction but also leads to substantial energy cost reductions for the hotel.
• Smart Residential Homes: For homeowners seeking a truly intelligent living space, the RCU1212 provides a single, reliable point of control. It can automate lighting, synchronize blinds with sunrise and sunset, and integrate with a central thermostat to optimize heating and cooling. The dual-input feature allows for a mix of traditional switches and automated controls, offering the best of both worlds.
• Healthcare Facilities: In healthcare settings, precise control and reliability are essential. The RCU1212 can manage lighting, blinds, and climate in patient rooms, ensuring a comfortable environment while simplifying controls for medical staff.
