CRS-HH-REL-10 – 10-channel relay module


SpaceLogic* CRS-HH-REL-10 relay module connects to the SpaceLogic RP-C Pro room controllers and enables the control of lights and blinds.

It supports high-voltage (120/240 VAC) blind motors. Other types of blind motors are supported by means of external relays. For more information, see the SpaceLogic Hardware Reference Guide.

It is part of the EcoStruxure™ Connected Room Solutions for Hotels and can be combined with other modules from this product range.

It is designed for hotel guest room applications.

It is not recommended to be used with the SpaceLogic RP-C Advanced room controllers for hotel applications.

* Formerly known as SmartX.


The relay module offers the following features:

  • Power and communications through the room bus

  • 10 relay outputs for the control of lights and blinds in the hotel guest room

  • 12 digital inputs offer more flexibility for different applications with in-wall switches or sensors. The digital inputs are SELV (Safety Extra-Low Voltage).

  • High-performance relays, with high inrush current capability, well suited for LED lighting applications

  • Status LED for the device

  • Rotary switch for address configuration

Connected Room Solutions for Hotels

This solution easily transforms hotels. Its extensive architecture is designed for a wide range of modular components including temperature, light and blind control interfaces, as well as bedside panels, sensors, thermostats, plus a wide range of HMIs (such as mechanical switches and Modbus glass touch panels). Get the latest wireless capabilities with the Commission mobile application for commissioning and the open protocols to interface with industry-standard IoT devices.

Room Bus

The RP-C Pro controller room bus supports up to nine connected RP controller expansion modules with the restrictions that are specified in the Connected Room Solutions for Hotels Supplementary Document Architecture Guidelines.

The Architecture Guidelines for Hotels is a supplementary document to the Architectural Guidelines - EcoStruxure Building Management.

Maximum total length of the room bus is 72 m (236 ft).
