Concept
This section provides grounding and power recommendations for system configurations with Central IO modules and PS-24V units.
Concept
Using the power rating for each of the modules (listed in the following table), accumulate the power consumed by the Smoke Control Server and Central IO modules. The PS-24V can supply up to 30W (~1.25A at 24 VDC). The 24 VDC from the PS-24V is delivered to all modules connecting on the bus on the right side of the PS-24V up to the next power supply module. You must add another PS-24V on the I/O bus to keep the load on the previous power supply at 30W or below.
Concept
The tables that follow provide a summary of all the equipment models you can interconnect to form the smoke control system.
Concept
The PS-24V is mounted on the Terminal Base model TB-PS-W1. The TB-PS-W1 appears similar to the TB-AS-W1 terminal base as seen in the figures in the section that follows.
Concept
The EcoStruxure BMS hardware includes several models of automation servers. These are the main distributed controllers in the system. They perform management, execution and supervision of the smoke control application programs. The server models approved for smoke control include the following:
Concept
You must install most of the controls products listed here in an enclosure that meets the following minimum criteria. After the criteria, several specific enclosure models are listed as examples of enclosures that meet the minimum criteria you can use for the smoke control system.
Concept
The EcoStruxure BMS hardware includes the Smoke Control Server, PS-24V power supply, terminal bases, and a variety of Central IO modules. The Smoke Control server is the main controller in the system and is always installed with a PS-24V supply forming the minimum configuration. A selection of Central IO modules is installed with the Smoke Control Server to provide inputs and outputs covering a wide variety of I/O types and capacities ranging from 8 channels up to 464 channels (29 Central IO modules of the 16 channel type + one additional PS-24V).
How to
You install a terminal base on a horizontal DIN-rail prior to connecting it to its neighboring terminal bases.
Concept
The devices are designed mainly for installing on DIN rails in a cabinet.
Concept
The terminal bases are used for SpaceLogic devices that are based on the patented two-piece design. The terminal base provides the I/O bus to the electronics module installed on the terminal base as well as to the SpaceLogic device installed to the right (next terminal base in the chain).
