Product Performance
High-speed synchronous link design can real-time mirror all data of master and standby controllers, ensuring complete consistency of their states and laying the foundation for seamless switching.
Millisecond-level fault switching capability can quickly trigger switching after detecting master controller failure, and the whole process is transparent to on-site I/O without process interruption.
Supports manual switching function, facilitating system maintenance, upgrade and testing, and enabling master-standby switching without shutdown.
Integrated multi-dimensional status monitoring, intuitively displaying operation, synchronization and master-standby status through front-panel LED indicators, enabling efficient fault diagnosis.
Deeply compatible with ControlLogix series power supplies and I/O modules, supporting redundant power supply configuration to build a system without single points of failure.
Wide temperature adaptation and industrial-grade protection allow long-term stable operation in harsh environments such as high dust and vibration, with reliability meeting the needs of critical control scenarios.
Supports network-level heartbeat monitoring, which can synchronously monitor the communication status of remote I/O and key equipment, further improving the overall availability of the system.
Standardized backplane interface requires no additional wiring for installation, with simple configuration and commissioning, reducing system integration and debugging costs.
