CRS-HH-REL-10

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

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.

The CRS-HH-REL-10 relay module is an RP controller expansion module. This means that it can also be combined with modules from the Connected Room Solutions for Buildings.

Relay Outputs

The CRS-HH-REL-10 relay module has 10 relay outputs, which are designed for control of lights and blinds.

For more information, see Relay Outputs on CRS-HH-REL-10 .

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 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 .

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 .

RP Controller Expansion Module Regulatory Compliance and Approvals

This section provides information on regulatory compliance and approvals for the RP controller expansion modules.

For more information, see RP Controller Expansion Modules Regulatory Compliance and Approvals .
