Human Machine Interface (HMI) - Accessories are integral parts of any machine or system. In this article, we will explore the NS12-KBA04 application field and working principle which falls under this HMIs.

The NS12-KBA04, also known as the mobile access control and remote data Terminal, is a compact, standalone unit that acts as the gateway devices for access control systems. It offers keypad input, contact and contactless card readers, integrated microphone, and loudspeaker ports. The NS12-KBA04 provides an integrated cryptographic authentication and authorization server functions by internally embedding sophisticated authentication algorithms. It is designed for inclusion in large-scale systems as part of access control systems, security systems, or closed-loop security systems. Its small form factor and fast processor make it ideal for heavy-duty operations workloads.

The NS12-KBA04 operates under two main modes. The first mode is static mode, where the user has to present tokens, cards, or credentials for authentication. Once the authentication is successful, the authorization process takes place. The authorization process is based on an integrated authorization server that authenticates access requests against the user database and determines whether the access request is authenticated or not. The second mode of the NS12-KBA04 is dynamic mode, where the system uses a smart card reader to read a personal identity number (PIN) from the smart card. Once the authentification is successful, the authorization process can start.

The NS12-KBA04 is equipped with an LCD touchscreen to display system statuses and provide operator control of the system. The device offers two physical security lock options, including a key driven deadbolt and an electromagnetic lock. The NS12-KBA04 is powered by a 12-volt DC power supply and can be integrated with an external auxiliary power source to extend its lifespan.

The main components of the NS12-KBA04 include a central processing unit, RAM and ROM memory, and EEPROM memory for storing configuration information. The device is designed for maximum flexibility, supporting multiple communication protocols such as Modbus, DNP3, and IEC 60870-5-103. It also supports external low voltage peripheral devices including card readers, magnetic card readers, RFID readers, and biometric readers.

The NS12-KBA04 is designed for operational security and easy implementation. Its open architecture allows it to be integrated with other systems, and its advanced cryptographic authentication capabilities ensure that all access to the system is secure. The NS12-KBA04 also supports the industry-standard AES encryption protocol.

The NS12-KBA04 is ideal for protecting sensitive areas and property, and is widely used in military, educational, and industrial applications, as well as in secure access control systems. Its robust design and easy installation make it a valuable asset for securing environments of all sizes.
