Concept
RP-C-EXT-BL-SMI-2-LV-PD
The RP-C-EXT-BL-SMI-2-LV-PD SMI blind module connects to the RP-C 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 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.

SMI LoVo Blind Outputs
The SMI low-voltage blind modules have two Blind outputs for control of motorized window blinds (drives) that are powered by 24 VDC. The Standard Motor Interface (SMI), LoVo version for DC low-voltage drives, is used to control the blind motors.
For more information, see SMI LoVo Blind Outputs .
RP Controller Expansion Module Digital Inputs
The RP controller expansion modules have digital inputs that can be used for sensing of dry contacts:
The light modules, blind modules, and the RP-C-EXT-REL-4 relay module have four digital inputs, which can be used in applications such as interfacing with light switches and window contacts.
The CRS-HH-REL-10 relay module has 12 digital inputs suitable for dry contact monitoring of switches and push buttons used for lighting control, window and door positions, and other functions in the hotel room.
For more information, see RP Controller Expansion Module Digital Inputs .
RP Controller Expansion Module Built-in Power Supply
The RP controller expansion light modules with power distribution capability, low-voltage blind modules, and SMI blind modules have a built-in power supply that can accommodate a nominal input voltage of 230 VAC at 50/60 Hz. Light modules without power distribution capability can accommodate a nominal input voltage of 100 to 277 VAC at 50/60 Hz.
For more information, see RP Controller Expansion Module Built-in Power Supply .
RP Controller Expansion Module Energy Metering
RP controller expansion modules with power distribution capability support energy metering, which means that the module can measure the electrical energy consumption and power demand for the equipment connected to and supplied by the module.
For more information, see RP Controller Expansion Module Energy Metering .
RP Controller Expansion Module Memory
RP controller expansion modules have two types of memory, flash memory and RAM.
For more information, see RP Controller Expansion Module Memory .
SMI Blind Modules Supported Building Standards
The SMI blind modules comply to version 3.0 of the SMI specification.
For more information, see SMI Blind Modules Supported Building Standards .
RP Controller Expansion Module Communication Ports
The RP controller expansion modules have two room bus ports (RJ45 receptacles), which enable connection to the RP-C controller and other expansion modules on the room bus through a daisy-chain configuration.
For more information, see RP-C Room Bus .
RP Controller Expansion Module Address Switch
Each RP controller expansion module has a rotary switch, which is used to give the device a unique address on the room bus.
For more information, see RP-C Room Bus .
RP-C 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.
For more information, see RP-C Room Bus .
RP Controller Expansion Module Pluggable Connectors
The RP controller expansion modules have PCB mounted connectors for the power input, outputs, and digital inputs. The PCB mounted connectors mate with pluggable connectors:
The light modules, blind modules, and the RP-C-EXT-REL-4 relay module have mechanically keyed and color-coded connectors, which allows the matching external connectors to be plugged in on site quickly and easily.
The CRS-HH-REL-10 relay module has PCB header connectors for pluggable screw terminal blocks, which are easy to install and remove from the device.
For more information, see RP Controller Expansion Module Pluggable Connectors .
RP Controller Expansion Module LEDs
There is one or more LEDs on the front panel of the RP controller expansion modules.
For more information, see RP Controller Expansion Module LEDs .
RP Controller Expansion Module Set Button
All RP controller expansion modules have a Set button on the front. The Set button is reserved for future use.
For more information, see RP Controller Expansion Module Set Button .
RP Controller Expansion Module Device Installation
The RP controller expansion module can be installed on a DIN rail or flat surface.
For more information, see RP Controller Expansion Module Device Installation .
Wiring
The wiring recommendations provide guidance regarding wiring of the Central IO modules, automation servers, BACnet/IP devices, RP controller expansion modules, and Operator Display.
For more information, see Wiring .
RP Controller Expansion Module Maintenance Modes
The RP controller expansion modules support different modes that can be used for maintenance purposes.
For more information, see RP Controller Expansion Module Maintenance Modes .
BACnet/IP Device Firmware Management
Using WorkStation, you can update the firmware of multiple BACnet/IP devices and their attached SpaceLogic Sensor devices and RP controller expansion modules at the same time with minimum downtime. In particular, the universal upgrade package simplifies the update process and requires minimal user involvement and coordination.
SpaceLogic Sensor devices and RP controller expansion modules are supported by the RP controller.
For more information, see BACnet/IP Device Firmware Management .
