English manual:
Triple module redundancy (TMR) : Three independent input channels are used to ensure the accuracy and reliability of the input signal through a comparison and voting mechanism.
Fail-safe design: When a fault is detected, the module can automatically switch to a safe state to ensure process safety.
Digital input: Each module typically contains multiple digital input channels to receive binary signals from field devices.
Channel isolation: Electrical isolation between input channels and from the rest of the system reduces interference and fault propagation.
Status indicator: Equipped with LED indicator to display the operating status of the module and each channel, which is convenient for on-site monitoring and troubleshooting.
Communication capability: Data exchange with other modules and controllers via the Tricon system's private communication network.
Hot swap: Modules can be replaced without shutting down the system, reducing downtime and maintenance costs.
Environmental adaptability: Designed for industrial environments with dust, water and electromagnetic interference resistance, suitable for harsh working conditions.
Safety and compliance: Meets international safety standards, such as IEC 61508 SIL 3, for the highest level of safety applications.
User interface and configuration: Configuration and monitoring via software tools such as Tricon Studio simplifies system integration and maintenance.
