KTG-PK Explosion-proof Computer

Product Description

KTG-PC computers are used where computer control of production processes, processing of information from external sensors, access to a computer network and databases in areas with a potentially explosive atmosphere are required.

The use of the latest advances in microprocessor technology has allowed us to maximize system performance, enabling us to solve complex problems in the calculation and control of technological processes directly at the facility.

Reduced power dissipation and heat dissipation of the central processing unit ensure reliable and fault-tolerant operation in the most challenging operating conditions, including near process facilities and in the harshest industrial environments requiring equipment resistance to extended temperature ranges, moisture, dust, shock, and vibration. The product successfully combines durability, mechanical strength, and ease of maintenance. The enclosure design provides quick access to functional units.

The motherboard's expandability allows for the installation of custom controllers and specific process control systems (for earthquake-resistant design, it is necessary to coordinate the mounting of the customer's equipment inside the enclosure).

For installation and ease of use of a computer at a technological facility, a frame/FRAME is manufactured according to the customer's drawings with the possibility of manufacturing a work surface for placing an intrinsically safe keyboard and mouse.

A special USB connector with a built-in barrier allows you to connect an intrinsically safe KKG-FN external flash drive and exchange data directly in a hazardous area.

Installing the KKG-SP explosion-proof infrared touch panel on a computer screen allows for quick data entry, production process management, and increased system productivity, while optimizing the operator-control system dialogue.

The built-in 12.1" LCD color monitor can be equipped with a light sensor upon customer request.

Scope: explosion-hazardous areas of premises and outdoor installations according to explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996) and areas dangerous for ignition of combustible dust, according to GOST IEC 61241-3-2011, hazardous industrial facilities of I, II, III, IV hazard classes, supervised by Rostekhnadzor of the Russian Federation and national technical supervision agencies of the CU and CIS countries.

The "X" symbol placed after the Ex marking of the device indicates that the device is prohibited from use in explosive mixtures of acetylene with air.
