Honeywell TC-RPCXX1 ControlNet Redundancy Communication Module

Product Description

The Honeywell TC-RPCXX1 is a ControlNet redundancy communication module for Experion C200 / C200E controller racks. It supports dual redundant ControlNet A/B media with 5 Mbps deterministic communication, synchronizing data between primary and backup controllers. It enables bumpless automatic switchover when the master controller fails, protecting continuous process control. It fits standard single-slot chassis mounting and features diagnostic LED indicators for module status, network activity and redundancy state. This legacy module is supplied as new surplus or fully tested refurbished spare parts for petrochemical, power and oil & gas DCS system maintenance and retrofit.

Product Functions

• Realize ControlNet redundant communication for Honeywell C200 / C200E redundant controller pairs
• High-speed synchronization of control logic, tag data and runtime status between primary and secondary processors
• Dual BNC ControlNet A/B ports for media redundancy to avoid single network cable failure
• Support bumpless automatic failover without process interruption during controller fault
• Onboard LED indicators for module health, network traffic and redundancy status diagnosis
• Hot-swappable design for replacement without shutting down the whole control rack

Application Scenarios

• Petrochemical refinery Experion PKS DCS continuous control and interlock systems
• Oil & gas compressor stations, pipelines and offshore platform control racks
• Thermal power plant boiler, turbine and auxiliary control systems
• Chemical, pulp and paper critical process control loops requiring high availability
• Spare replacement and repair of existing Honeywell C200/C200E ControlNet redundancy systems
