Application Scenarios
Ideal for oil & gas refineries, chemical processing plants, power generation facilities, and offshore platforms where remote I/O placement reduces wiring costs while maintaining safety integrity. The 2101 RXM enables flexible system topology in hazardous area installations, supporting Emergency Shutdown (ESD) and Fire & Gas (F&G) detection systems.
Integration Solutions
Seamlessly integrates with Triconex main processors (3008, 3009, 4119A) and I/O modules including digital input/output, analog I/O, and specialty modules. Compatible with existing Tricon chassis configurations, enabling phased system expansions without controller replacement. Works with Triconex 4201 RXM for multi-drop network architectures.
Common FAQs
Q: Can the 2101 support redundant communication paths?
A: Yes, dual RXM configuration provides fault-tolerant communication with automatic failover capability.
Q: What cable types are compatible?
A: Supports both copper twisted-pair (RS-485) and fiber optic cabling for extended distances and EMI immunity.
Q: Is hot-swapping supported?
A: The module supports online replacement in redundant configurations without system shutdown.
