What industrial-grade features are incorporated in the KTB 122?
Equipped with a low-power processor, it is suitable for scenarios with limited space and strict heat dissipation requirements, such as rail transit on-board equipment and small control cabinets.
It provides 1 DDR3/4 SODIMM slot, dual storage interfaces (2.5-inch hard drive + mSATA) and a Mini-PCIe expansion slot, balancing expansion needs with a miniaturized design.
It supports a watchdog function (programmable from 1 to 255 seconds), enhancing the stability of system operation.
The operating temperature range can reach -20℃~60℃, enabling stable operation even under the harsh conditions of frequent high and low temperature alternations in industrial environments.
The storage temperature range is further extended to -30℃~70℃, fully meeting the requirements of various complex scenarios.
Convenience of Deployment
The ultimate lightweight design is suitable for embedded scenarios with limited space, such as rail transit on-board equipment and small control cabinets.
Low-Power and Long-Term Operation
The fanless design reduces mechanical failures, while the wide-temperature characteristics ensure stable operation in high and low temperature environments, thus guaranteeing long-term work in industrial scenarios.
Efficient Adaptation to Multiple Scenarios
Dual-display, dual-network, dual-serial configurations meet device connectivity and data interaction needs in intelligent transportation and other fields without additional hardware adaptation.
Balance Between Expansion and Compatibility
Rational interface and slot configurations balance miniaturization with essential expansion capabilities, ensuring compatibility across diverse systems and enhancing operational flexibility.
Application Cases
The following are real application cases of KTB in various industries.
Serbia Industrial Automation: Kangtai Bokong 18-inch Industrial Panel PC Powers Boiler Control Systems
