ABB GJR5253000R0270 07KT97 Central Unit

Basic Information:

Model: GJR5253000R0270, belongs to the 07KT97 series of central units.

Place of Origin: Usually made in Sweden.

Weight: about 0.8kg.

Performance features:

Processor and Memory: High-performance processor, equipped with 256KB user data memory and 480KB user programme memory, which can meet the needs of more complex control programmes and large amounts of data storage to ensure the efficient and stable operation of the system.

Input and output configuration:

Analogue input and output: 8 analogue input channels, signal types can be configured as 0...+5V, -5...+5V, 0...+10V, -10...+10V, 0...20mA, 4... ...20mA, Pt100 (2-wire or 3-wire), etc.; 4 analogue output channels, the output signal range of - 10...+10V, 0...20mA, can meet a variety of sensors and actuators signal access and control needs.

Digital input and output: 24 digital input channels and 16 digital output channels, can be easily connected to digital sensors, switches, relays and other equipment, to achieve the switching control and status monitoring of equipment.

Communication interface: Support Ethernet TCP/IP communication protocol, which can realise fast data communication with host computer, other controllers or intelligent devices, which is convenient for building distributed control system and meets the communication requirements in different industrial scenarios.

Application areas:

Industrial automation control system: widely used in various industrial production processes, such as chemical, pharmaceutical, food and beverage industries, as the core control unit, to achieve accurate control and monitoring of production equipment, improve production efficiency, product quality and stability of the production process.

Process control field: in the petrochemical, metallurgical, electric power and other industries in the production process control, temperature, pressure, flow and other physical quantities for accurate control, through its rich input and output interfaces and powerful computing capabilities, to achieve real-time monitoring of process parameters and automatic adjustment.

Intelligent building automation system: It is suitable for building automation system in intelligent buildings, centralised control and management of air-conditioning system, lighting system, ventilation system, etc. It automatically adjusts the operating status of the equipment according to the environmental parameters and users' demands, improves the energy efficiency and comfort of the building, and realizes energy saving, emission reduction and intelligent management.
