RP-C-EXT-BL-SMI-2-LV-PD

RP-C-EXT-BL-SMI-2-LV-PD – SMI low-voltage blind module

RP-C-EXT-BL-SMI-2-LV-PD – SMI low-voltage blind module

Introduction

SpaceLogic* RP-C-EXT-BL-SMI-2-LV-PD SMI blind module connects to the SpaceLogic RP room controllers and provides I/O expansion for control of DC low-voltage motors (drives) with SMI LoVo (Standard Motor Interface for low-voltage applications).

The SMI blind module is an SMI certified and registered actuator (controller) that complies to SMI version 3.0. SMI 3.0 offers simplified maintenance, new functions, improved robustness, and high compatibility. The module can be used with products of SMI version 2.0 because the interface is backward compatible.

The SMI low-voltage blind module enables control and power supply (24 VDC) of motorized venetian blinds, roller blinds, pleated blinds, and other shade products (typically for interior use).

The SMI blind module is part of the RP controller expansion modules for connected room solution and can be combined with other modules from this product range.

* Formerly known as SmartX.

Features

The SMI low-voltage blind module has the following features:

  • Power and communications through the room bus

  • One SMI channel, which is split into two outputs, for SMI LoVo control of 24 VDC powered blinds (opening, closing, positioning)

  • Four digital inputs for connection of blind switches and window contacts. The digital inputs are SELV (Safety Extra-Low Voltage).

  • Measurement of energy consumption per module

  • Wieland connectors for quick and easy installation

  • Engage mobile application for room comfort settings

  • Status LED for the device

  • One status LED for each blind output

  • Rotary switch for address configuration

SMI LoVo blind control

The SMI interface has the following features:

  • Up to 16 blind motors or drives can be controlled electrically in parallel (provided the load limits are not exceeded)

  • High-precision intermediate positioning

  • Motor feedback with diagnostic information

Room bus

The RP controller room bus allows RP controller expansion modules to be connected to the controller for people counting, motion detection, luminosity and sound pressure level measurements, Bluetooth Low Energy based applications, and control of electric lights and window blinds.

The RP-C Pro controller room bus supports up to nine connected RP controller expansion modules with the following restrictions:

  • Maximum of two DALI light modules

  • Maximum of two SMI blind modules

  • Maximum of seven Multi-sensor or Insight-Sensor devices

The RP-C Advanced controller room bus supports up to six connected RP controller expansion modules with the following restrictions:

  • Maximum of two DALI light modules

  • Maximum of two SMI blind modules

  • Maximum of four Multi-sensor or Insight-Sensor devices

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

Engage mobile application

The Engage mobile application enables control of room temperature, fan speed, lights, and blinds/shades directly from a smartphone. A user can manage these settings when the application is connected to the RP-C controller.

The Engage mobile application is free and available for download from Google Play and Apple App Store.

For more information, see the Engage Specification Sheet.

The external connectors need to be ordered separately. The connectors can be ordered in quantities of 50 or 100 from Schneider Electric using the above part numbers. The connectors can also be ordered directly from Wieland using the above reference numbers. For more information, see the Wieland Electric web site.

Compatibility with the type and characteristics of the blind motors should be verified at an early stage in your project. In case of uncertainty, additional testing may be required.
