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 and Multi-sensor Memory

RP controller expansion modules and multi-sensor have two types of memory, flash memory and RAM.

For more information, see RP Controller Expansion Module and Multi-sensor 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 and Multi-sensor Communication Ports

The RP controller expansion modules and multi-sensors have two room bus ports (RJ45 receptacles), which enable connection to the RP-C controller and other expansion modules and multi-sensors on the room bus through a daisy-chain configuration.

For more information, see RP-C Room Bus .

RP Controller Expansion Module and Multi-sensor Address Switch

Each RP controller expansion module and multi-sensor 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-C room bus allows RP controller expansion modules and multi-sensors to be connected to the controller for motion detection, luminosity measurements, communication with remote control (RP-C-RC-BLE), 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, and RP controller expansion modules, and Operator Display.

For more information, see Wiring .

RP Controller Expansion Module and Multi-sensor Maintenance Modes

The RP controller expansion modules and multi-sensors support different modes that can be used for maintenance purposes.

For more information, see RP Controller Expansion Module and Multi-sensor 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, RP controller expansion modules, and multi-sensors at the same time with minimum downtime. In particular, the universal upgrade package simplifies the update process and requires minimal user involvement and coordination.

Tip:

SpaceLogic Sensor devices, RP controller expansion modules, and multi-sensors are supported by the RP controller.

For more information, see BACnet/IP Device Firmware Management .
