Product Introduction:
The Triconex 3351 Analog Input Module is a high-performance module designed for industrial automation and safety systems. It features three independent input channels that convert variable voltage signals into digital values. These values are transmitted to the system’s three MPs (Microprocessor Units) as needed, with a mid-value selection algorithm ensuring that data integrity is maintained. This module is equipped with fault detection for each input channel and is capable of continuous operation even if one or more channels fail, making it ideal for critical applications requiring high availability and reliability. Hot sparing support allows for online replacement of faulty modules, ensuring uninterrupted operation.
Applications:
- Process control systems
- Safety critical applications
- Industrial automation systems
- Oil & Gas, Chemical, Power, and Petrochemical industries
- Systems requiring high availability and fault tolerance
Product Advantages:
- Reliability: Continuous diagnostics ensure fault detection on each channel. The module continues to operate normally despite faults, providing high system availability.
- Fault Tolerance: The system allows operation with single or multiple faults without compromising functionality.
- Hot Sparing: Facilitates easy and uninterrupted replacement of faulty modules without shutting down the system.
- Scalable: Multiple modules can be deployed in the system to accommodate more inputs as required.
- Error Detection: Fault indicators point to specific channel failures, enabling precise troubleshooting.
- Mechanical Keying: Prevents improper installation by ensuring the module can only be installed in the correct baseplate.
