Detailed data
Triconex 3721 TMR Analog Input Modules
The Triconex 3721 TMR analog input module is used for critical process control and monitoring. It is designed to process analog input signals in a triple modular redundant configuration, providing high reliability and fault tolerance for applications requiring a high level of safety integrity.
Analog input modules support hotspare capability which allows online replacement of a faulty module. The analog input module requires a separate external termination panel (ETP) with a cable interface to the Tricon backplane. Each module is mechanically keyed for proper installation in a Tricon chassis.
It can connect a variety of field devices to the Triconex safety system. The 3721 module is specifically designed to handle analog input signals, 4-20 mA, 0-10 VDC and other standard industrial analog signals.
The 3721 TMR analog input module supports safety integrity level . The TMR architecture helps meet the necessary SIL 3 safety requirements, ensuring that the system continues to operate even in the event of a fault. It also ensures high availability.
Frequently asked questions about the product are as follows:
-What are the benefits of triple module redundancy?
The TMR design significantly enhances the fault tolerance of the system. This ensures continuous safe operation and minimizes the risk of failure in critical safety applications.
-What types of sensors can be connected to the 3721 analog input module?
The 3721 supports a wide range of analog sensors, including pressure transmitters, temperature sensors, flow meters, level sensors, and other field devices that produce analog signals.
-Are Triconex 3721 modules hot-swappable?
Hot-swappable is supported, which allows modules to be replaced or repaired without shutting down the system, ensuring continuous operation in critical applications.
