ABB Advant Controller 450 User’s Guide

rich power input options, so that it can be adapted to different industrial site power supply conditions.

Output Parameters: Take the voltage regulator unit for DC input/DC output as an example, when inputting 24VDC, 

the output is 5V DC regulated and the output current can be up to 10A, and it is equipped with 5A standby fuse, 

which can provide stable power supply for each module of the system.

Redundant Configuration: 

Supporting power supply redundancy, different power input types can be combined to achieve double redundant power supply, 

ensuring that the system can still work normally when a single power supply fails, improving the stability and reliability of the system power supply.

(III) Communication module

Type and Interface

Serial communication: V.24/RS 232 interface module (e.g. CI 531) with 2 communication channels, up to 4 can be installed, 

used for low-speed data communication with external devices supporting RS232 protocol, such as some sensors, small controllers and so on.

Fieldbus communication: Supports MasterBus 300/300E, Advant Fieldbus 100, PROFIBUS and other fieldbus protocols. 

Through the corresponding communication sub-module, high-speed data interaction with distributed I/O stations, 

other controllers and intelligent devices can be realised to build complex industrial control systems. Among them, 

Advant Fieldbus 100 uses twisted-pair media or has media redundancy, bus redundancy and other connection modes, 

with long communication distance and high reliability.

Other communication: Support GCOM protocol for communication with external computer and AdvaSoft for Windows software; 

through MVI (Multi - Vendor Interface) protocol, it can communicate with other brands of control systems (such as through MODBUS I, 

Siemens 3964R, or Allen-Bradley's DF1 protocol) to enhance the compatibility and openness of the system. 

This enhances the compatibility and openness of the system.

Quantity limitation: communication sub-modules are installed on sub-module carriers (e.g. SC 510/SC 520, maximum 6 or 7), 

and a total of 12 or 14 communication sub-modules can be installed, 

which meets the diversified communication connection requirements in different industrial scenarios.

(iv) I/O system

S100 I/O

Number of racks and modules: 

Up to 5 S100 I/O racks can be connected, and each rack can accommodate various I/O modules, and a total of up to 100 S100 I/O modules can be installed. 

The maximum number of analogue I/O modules per type is 32, and the maximum number of digital I/O modules per type is 48.

Communication distance: With the optical bus extension technology, S100 I/O racks can be distributed up to 500 metres away from the CPU rack, 

effectively reducing the amount of field wiring and making it suitable for industrial scenarios with a wide distribution of equipment.

I/O capacity: S100 I/O system can handle a large number of I/O signals, 

providing the basis for data acquisition and equipment control in industrial production.

S800 I/O

Number of Stations and Modules: 

Each Advant Fieldbus can connect up to 79 S800 I/O stations, and each I/O station can be installed with up to 246 S800 I/O modules.

Communication capability: Communicate with the controller via Advant Fieldbus 100, with fast transmission rate and high reliability, 

and can transmit a large amount of field data in real time.

I/O capacity: build a powerful I/O system together with S100 I/O, making the total number of I/O channels of the whole system as high as 5700, 

among which the maximum number of AI channels (including calculated value) is 910, 

the maximum number of AO channels (including calculated value) is 963, the maximum number of DI channels (including calculated value) is 2,340,

 the maximum number of DO channels (including calculated value) is 1,489, 

which can meet the complex I/O requirements of large-scale industrial automation system. 

This can meet the complex I/O requirements of large-scale industrial automation systems.

Special I/O modules: There are special types of I/O modules such as Pt100, thermocouple and pulse input modules, 

which can be used to meet the needs of special industrial applications such as precise temperature measurement and pulse signal counting. 

For example, Pt100 modules can accurately measure temperature and provide accurate data for temperature control in industrial production processes.
