EcoStruxure BMS Hardware Overview

Electronics Module Features

There are three type of electronics modules included in the Automation Server module family including the PS-24V Power Supply module, the Smoke Control Server, and 17 models of the I/O modules. All of these modules share the following common features.

Because critical applications require 24-hour operation, Schneider Electric designed the electronic modules for hot-connection of terminal bases and hot-swapping of the modules to their bases. This design ensures continuous power and communication during service operations.

The auto-addressing feature eliminates the need for setting DIP switches or pressing commission buttons. With the Automation Server family, each module automatically knows its order in the chain and assigns itself accordingly. This significantly reduces engineering and maintenance time.

Fasteners easily snap into a locked position for panel installation. The fastener has a quick-release feature for easy DIN-rail removal. The modules use common 35mm DIN rail.

Protection components on the inputs and the outputs protect against high-voltage, short-duration transient events. The current inputs are protected against over current.

The Automation Server module family uses built-in connectors for single row connectivity, side by side. If a panel size requires multiple rows, S-cable extension cords are available.

The Automation Server module family are all powered by 24 VDC supplied by the PS-24V module, which in turn, is powered by 24 VAC. For UL 864 compliance, the 24 VAC must be provided by one of the approved transformers. For more information, see Transformers . 

The module family shares a common environment specification:

• Storage: -20°C to +70°C

• Operating: 0°C to +50°C

• Humidity: up to 95% RH, non-condensing

Modules have housings that share plastic resin type and are molded with the same mechanical size dimensions:

• Plastic Type: Eco Friendly ABS/PC

• Plastic Flammability: UL94-5V

• Enclosure Rating: IP20

• Mechanical Size– Inches 3.6 W x 4.5 H x 2.5 D (Millimeters: 90 W x 114 H x 64 D)

Power Supply

A PS-24V power supply module is required for each Smoke Control Server. The PS-24V plugs into the model TB-PS-W1 DIN rail mounted terminal base. The right side of this terminal base directly mates with the TB-AS-W1 terminal base holding the Smoke Control Server. The PS-24V accepts input power from a 24 VAC transformer and consumes a maximum power of 60VA. The unit provides a 24 VDC (30W max.) output to the terminal base. This power is delivered to the Smoke Control Server and other modules positioned to the right of the PS-24V terminal base.

AS-P-SMK and AS-SMK Automation Servers

The Automation Server and AS-P are Schneider Electric manufactured, embedded devices that generally serve as the lowest tier servers within the EcoStruxure Building Management System. Typically, they control and supervise HVAC equipment using I/O modules with connected field devices, such as sensors and actuators.

In a smoke control system, the AS-P (AS-P-SMK) or Automation Server (AS-SMK) operate as the main controllers.

Smoke Control Server Communication

The Automation Server and AS-P with the SMK suffix (AS-SMK and AS-P-SMK), refer to the UL 864 listed model which is the version you must apply in smoke control applications. As indicated previously, when the Automation Server (AS-SMK) and AS-P (AS-P-SMK) are discussed together, they will be referred to as Smoke Control Servers.

Common I/O Module Features

The I/O modules include these common features:

• Terminal base mounting

• Hand/Off/Auto switches

All I/O modules plug into the same model terminal base model TB-IO-W1 and spread their unique combination of inputs and outputs over the 24 wiring terminals provided on each base.

All I/O modules that provide analog or digital outputs include an optional Hand/Off Auto switch. The front panel of the I/O module with the -H model number suffix includes Hand/Off/Auto (HOA) switches that provide override control of the outputs. For Digital output types, the switch will accommodate the positions to select automatic operation (output driven by the Automation Server or AS-P), the override ON mode and the override OFF mode. For Analog output types, the switch will accommodate the positions to select automatic operation (output driven by the Automation Server or AS-P) and hand/manual override mode. When in the hand override position, a rotary potentiometer is provided to manually control the output voltage or current over the full range.

The Automation Server or AS-P reads the position of the HOA switch and enables the functional supervision required for UL864 compliance. While the HOA switches are useful during system installation and configuration, all switches associated with smoke control equipment must remain in the automatic position after system commissioning. All switches that affect smoke control equipment must be supervised by the Automation Server or AS-P and the status of the HOA switches reported to the Automation Server or AS-P managing the FSCS panel. If any HOA switches affecting smoke control equipment are detected in a position other than automatic, the Automation Server or AS-P must indicate a fault on the FSCS panel with visual and audible annunciation. You may use the common equipment fault LED as a visual indicator. However, a preferred scheme includes a separate LED indicator identified as an HOA Override Fault.

A summary of the I/O modules included in the smoke control system follows.
