2.Main Features

Triple Redundancy Design:The 3704E module uses TMR(Triple Modular Redundancy)technology,with three independent processing units to collect and verify input signals,thereby improving the system’s fault tolerance and ensuring data accuracy and reliability.

High-density signal acquisition:The module supports 32 independent digital input signals,provides high-density signal acquisition capabilities,and can monitor and process inputs from multiple sensors and switches.

Hot-swap function:The 3704E supports hot-swap function,which allows modules to be replaced without shutting down the system,reducing downtime and improving maintenance efficiency.

Built-in self-check function:The module has a built-in self-check function that can continuously monitor the health of the system,detect and report faults in a timely manner,and help prevent problems in advance.

High compatibility:The module is fully compatible with other modules and controllers of the Triconex system and can be easily integrated into existing control systems.
