KNX and BACnet

Intelligent building automation

KNX is a standard protocol for intelligent control

and supervision of all systems in a building.

The KNX standard has already been used success

fully for over 20 years in the building automation

segment. ABB has a huge number of KNX devices

in the portfolio and great experience with KNX solutions.

By adding the KNX protocol to AC500 V3. ABB can

now offer a powerful and freely programmable

KNX building automation controller with flexible

expandable I/O modules. With KNX and BACnet

the AC500 product portfolio is now also available

for innovative building automation.

The proven ABB AbilityTM Automation Builder

engineering tool is integrated with the ETS and

ETS apps to assist you in building your application.

MQTT

Cloud connectivity

MQTT is a TCP/IP messaging protocol mainly

used for lightweight messaging to the cloud.

In the environment of MQTT, edge devices like

controllers act as clients and communicate with

a broker situated in the cloud.

They publish data based on events using topics.

Other clients like SCADA systems or monitoring

applications can subscribe to these topics and

receive data as they arrive. This enables the easy

and low-bandwidth connection of many devices.

AC500 V3 uses TLS encryption to establish secure

communication.

Secure connectivity

Remote units

AC500 works as edge-gateway and is directly

connected to the cloud. Security is established

through TLS encryption.

• No additional gateway required

• Low latency

Application:

Small systems with non-critical data transfer.

Network security

Connection of the whole AC500 network to the

cloud using a separate gateway. Enhanced

security is provided through additional firewall

and/or VPN.

• Advanced level of security

• Easy integration of many edge devices

Application:

Large systems with many devices which need

higher protection.

OPC UA server

Data connectivity

OPC UA, Unified Architecture, is a protocol for

information exchange for industrial communica

tion. This means that OPC UA is a standardized

vendor-independent Ethernet protocol, scalable

for a lean data access between a client and server.

OPC UA is widely adopted in many different

industries like automotive, food and beverage,

utilities and infrastructure.

OPC UA fulfills the requirements of IoT and

Industry 4.0. Security is established based on

certificates. AC500 V3 supports the OPC UA

services “Data access”, “User management” and

“Alarm and conditions”.

Features

– Pre-molded shielded separable connectors are made of EPDM rubber with three layers: conductive inner layer, insulating layer and conductive outer layer.

The three layers of rubber are vulcanized to make the interface between the layers as perfect as possible. It has good resistance to UV, ozone and tracking.

– Supplied in three-phase kits with crimped cable lugs, stress-graded adapters designed to ensure reliable installation

– Single- or three-pole cable grounding kit must be used (can be ordered separately)

Preformed shielded detachable connectors

Applications

Preformed shielded breakaway connectors for 12kV XLPE insulated single or three core

cables with aluminum or copper conductors. Suitable for EN 50181 Type C interface

Standard

– GB/T12706.4

– IEC 60502.4

Voting Units

The Voting Units SS822Z, SS823 and SS833 have been

specifically designed to be employed as a control

unit within a redundant power supply configuration. The output connections from two Power Supply

Units are connected to the Voting Unit. The Voting

Unit separates the redundant Power Supply Units, supervises the voltage supplied, and generates supervision signals to be connected to the power consumer.

Green LED’s, mounted on the front panel of the voting unit, provide a visual indication that the correct

output voltage is being delivered. Simultaneously

with the green LED illuminating, a voltage free contact closes the path to the corresponding “OK connector”. Voting Unit trip levels, are factory preset.

High Integrity

The AC 800M High Integrity and the connected S880

High Integrity I/O system (including field power)

shall be supplied from a SELV or PELV power supply

(e.g. SD83x) connected through the power voter

SS823. The SS823 Voting Unit has double overvoltage protection circuit, limiting the output voltage to

max 30 VDC. It is also able to detect both short and

open circuit in the voting element.

The SS822Z and SS823 units is also G3 compliant.

Key Features

• Simple DIN-rail mounting

• Class I Equipment, (when connected to Protective Earth, (PE))

• Over-voltage Category III for connection to primary main TN network

• Protective separation of secondary circuit from primary circuit

• Accepted for SELV and PELV applications

• The output of the units is protected against over

current (current limit) and over voltage (OVP)

• SD834 can be connected in parallel to increase output power

• Both a.c. and d.c. input at SD831 and SD834

• Floating DC-OK relay contact at SD834

Power Supplies

The SD83x and SD85x Power Supply Units are designed to meet all the applicable electrical safety

data stated by the EN 50178 harmonized European

Standard Publication and the additional safety and

function data required by EN 61131-2 and UL 508.

The secondary output circuitry is accepted for SELV

or PELV applications.

They are switch-mode Power Supply Units which

convert the mains voltage to 24 volts d.c. These

power supplies can be utilized for non-redundant

and redundant applications. Redundant applications

require diode voting units SS823 or SS832.

With the type SD83x series Power Supply Units,

there is no requirement for the installation of a

mains filter. They provide a soft start feature; power-on of an SD83x will not trip fuses or earth-fault

circuit breakers. The SD822Z is also G3 compliant.

The range also supports power supply configurations of the AC 800M and S800 I/O based IEC 61508-

SIL2 and SIL3 rated solutions. A Mains Breaker Kit for

DIN Rail is also available for our power supplies and voters.

Scales from low cost, standard function to high end features like hot-swap, HART, time tagging, redundancy down to I/O channel.

S800 I/O is an open comprehensive, distributed, process I/O system that communicates with

controllers by direct connection or over industry-standard field buses.

Thanks to its open connectivity it fits a wide range of process controllers from ABB and others.

By permitting installation in the field, close to sensors and actuators, S800 I/O reduces the installation cost by reducing the cost of cabling.
