Biometric Authentication System for PLC and SCADA

 Biometric Authentication System is designed to enhance the security and access control of PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition) systems. By integrating biometric authentication system, we provide a robust and reliable solution that ensures only authorized personnel can access critical industrial control systems.

The product is tested with all PLC’S and supports multiple interface options.

ORDER CODE: RDL810


Features: 

  • Fingerprint scanning is the sole method used for biometric authentication..
  • Integration with existing PLC and SCADA systems for seamless implementation.
  • Secure storage and encryption of biometric data.
  • User management and access control functionalities.
  • Real-time monitoring and logging of access events.
  • Centralized administration and reporting capabilities.
  • Fingerprint enrollment: Max 150 Users.
  • Memory : 16GB.
  • Communication : RS485 MODBUS RTU, MODBUS TCP, RS232, USB.
  • Power supply: DC 24V.

Benefits

  • Higher level of security and access control for critical industrial control systems
  • Prevention of unauthorized access and potential threats to PLC and SCADA systems
  • Reduction in the risk of data breaches and sabotage
