Basic information

Part number: GJR5253000R0276, belonging to ABB's Advant OCS series, is a central unit with Ethernet - ARCNET under the model number 07KT97.

Place of Origin: Typically produced in Sweden.

Dimensions and weight: Estimated shipping dimensions are approximately 6.0 inches x 4.0 inches x 10.0 inches (15.2 cm x 10.2 cm x 25.4 cm), and weight is approximately 2 pounds 0.9 ounces (0.9 kg).

Performance Features

Processor and memory: 32-bit RISC processor, equipped with 256KB of data memory and 480KB of programme memory, can efficiently handle complex control tasks and large amounts of data storage requirements, to ensure stable operation of the system.

Input and output configuration:

Analogue input and output: 8 analogue input channels and 4 analogue output channels, with input and output signals of 0-10V, 4-20mA, etc., which can satisfy the measurement and control of various physical quantities such as temperature, pressure and flow.

Digital input and output: 24 digital input channels and 16 digital output channels, which can be easily connected to digital sensors and actuators, such as limit switches, relays, etc., to achieve switching control and status monitoring of equipment.

Communication interface: Support Ethernet and ARCNET communication protocols, and also has RS-232, RS-485 and other communication interfaces, which can realise fast and stable data communication with other devices, and make it easy to build a distributed control system, and interact with the host computer, other controllers or intelligent devices.

Operating temperature range: the working temperature range is from 0°C to 55°C, and the storage temperature range is from -25°C to 75°C, which can adapt to a wide range of industrial ambient temperature conditions and ensure stable and reliable operation in different working scenarios.

Application Areas

Industrial automation control system: In the chemical, pharmaceutical, food and beverage and other industrial production processes, as the core control unit, to achieve precise control and monitoring of production equipment, improve production efficiency, product quality and stability of the production process.

Process control field: Widely used in the process control system for precise control of temperature, pressure, flow and other physical quantities, such as petrochemical, metallurgy, electric power and other industries of the production process 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 realises energy saving, emission reduction and intelligent management.
