Core Features

Triple Redundancy Design

High-Speed Digital Input

• Supports 32 digital input channels, configurable as TTL or dry contact inputs.
• Response time per channel is <1ms, suitable for high-speed event detection (e.g., emergency shutdown signals, valve status monitoring).

Fault-Safe Design

• Automatically switches to a safe state in case of faults, compliant with IEC 61508/SIL3 and ISA 84.01 standards.
• Built-in self-diagnosis function for real-time monitoring of module health.

Communication Interfaces

• Communicates with the main controller via the Tricon system backplane, supporting redundant communication paths.
• Optional fieldbus interfaces (e.g., Profibus DP, Foundation Fieldbus) are available.

Environmental Adaptability

• Operating temperature range: -40°C to +70°C, resistant to vibration and shock, meeting the requirements of harsh industrial environments.
