EAE RCU1212 KNX Actuator: Integrated 12 Outputs and 12 Inputs

The EAE RCU1212 KNX Actuator is a powerful and highly versatile KNX device designed to dramatically simplify and enhance building automation in modern spaces. As an all-in-one solution, it consolidates a wide range of control functions—both actuation (outputs) and signaling (inputs)—into a single unit, eliminating the need for multiple discrete devices. This EAE RCU1212 KNX Actuator is expertly engineered to control essential room elements, including lighting, blinds, and fan coils, while also providing a rich interface for switches and sensors. It is an ideal solution for applications in hotels, residential apartments, and commercial buildings.

The RCU1212 is built for easy installation and robust performance. Designed for mounting on a 35mm DIN rail, it fits seamlessly into a standard electrical cabinet. Crucially, the RCU1212 is powered directly by the KNX bus, which simplifies the wiring process and reduces the need for additional power sources.

1. Core Specifications of the EAE RCU1212 KNX Actuator

The RCU1212 is a sophisticated piece of technology defined by its dual functionality: a large number of high-capacity outputs paired with extensive input channels.

Dual-Purpose Design: 12 Outputs and 12 Inputs:

The EAE RCU1212 KNX Actuator is equipped with 12 independent relay outputs, each capable of handling up to 16A. Additionally, it features 12 independent digital inputs, making it a powerful universal interface for conventional switches and dry contact signals. This combination provides both high-density actuation and input capability in one module.

Versatile Output Functions:

The 12 outputs are grouped into three independent output channels, providing exceptional flexibility. The unit can be configured to act as:

• Switching Outputs (x4): For on/off control of lights and other electrical loads.
• Blind Control (AC x2, DC x1): To precisely manage AC-powered and DC-powered blinds and shutters.
• Valve Control (2-Point x2, 3-Point x1): To manage two-pipe or more complex three-pipe fan coil systems for heating and cooling.

Integrated Logic and Advanced Input Functions:

Thanks to the 12 digital inputs, the RCU1212 can serve as a universal interface, enabling the connection of standard push-buttons, switches, or dry contacts to the KNX system for functions like scene control, dimming, and value transfer.

2. Application Scenarios: Where the EAE RCU1212 Excels

The RCU1212 is a versatile solution that offers significant benefits in terms of efficiency, cost savings, and reduced installation complexity.

Key Applications and Benefits:

• Hotel Guest Rooms: Consequently, the RCU1212 is ideal for Guest Room Management System integration, managing 12 output loads (lights, valves) while receiving commands from 12 separate inputs (door contact, bedside switches).
• Commercial Buildings and Offices: Used for zoned control, managing up to 12 lighting circuits or blinds while consolidating inputs from multiple local switches in meeting rooms or open-plan areas.
• Integrated Logic and Functions: Furthermore, features like Staircase Function and External Logic allow for sophisticated, programmable automation routines based on inputs from KNX Sensors.
