Overview

Core Technical Specifications

1. Network & Redundancy Performance

• Supported protocol: ControlNet industrial deterministic real-time bus
• Dual independent BNC media ports (Media A / Media B) for redundant trunk wiring
• Automatic dual-link detection & bumpless switchover; zero process data interruption during single cable/network fault
• Deterministic scheduling cycle: 5/10/20ms configurable, consistent with DCS process control timing requirements
• Supports redundant ControlNet trunk topology, matches standard ControlNet coaxial trunk cable TC-KCC900

2. Electrical Hardware Parameters

• Power supply: 24VDC backplane power from C300 rack, power consumption ~12W
• Isolation: 2500VDC galvanic isolation between ControlNet bus and controller backplane, suppress grid & inverter EMI interference
• Connectors: Two industrial BNC sockets for ControlNet drop cables; RJ45 Ethernet port for local module commissioning
• Conformal coated PCB version optional for high-humidity, corrosive chemical environments
• Weight: 0.45kg; plug-in rack-mounted, hot-swappable with RIUP technology (no rack power-off during replacement)

3. Mechanical & Environmental

• Form factor: Standard C-series vertical slot module for C300 controller chassis
• Protection grade: IP20 (cabinet internal installation)
• Operating temperature: 0℃ ~ +60℃; storage: -40℃ ~ +85℃
• Humidity: 5%–95% RH non-condensing
• Certifications: CE, UL508, FM Class I Div.2 hazardous area approval

4. Status Diagnosis

• Front panel multi-color LED indicators: Module run status, Media A/B link fault, communication active, backplane error
• Real-time network fault diagnosis uploaded to Experion SCADA: cable open/short, trunk repeater failure, signal attenuation alarm
• Supports remote parameter configuration via Control Builder software without on-site wiring adjustment

Key Features

1. Full dual-media redundant communication
    
   Two completely isolated ControlNet signal channels, if one cable, repeater or network branch fails, the system instantly switches to the backup link without stopping production control loops.
2. Hot-swap maintenance capability
    
   Module can be replaced online without shutting down the C300 controller, greatly reducing downtime for critical process plants.
3. Strong anti-interference design
    
   Integrated high-voltage isolation and shielded signal circuit, stable operation in environments with a large number of frequency converters, motors and welding equipment.
4. Integrated fault alarm output
    
   Link failure signals can be uploaded to HMI or external alarm light systems for on-site maintenance prompt.
5. Unified C300 rack architecture
    
   Plug-and-play with all C300 series controllers and I/O modules, consistent with the whole Experion PKS system spare parts management standard.

Matching Accessories

• Redundant ControlNet drop cables: BNC double-head cable (matching TK-CCR014 dual BNC ports)
• ControlNet trunk cable: TC-KCC900 certified coaxial trunk wire
• ControlNet repeaters & terminal resistors for long-distance cabinet interconnection

Application Scenarios

• Petrochemical refinery, chemical plant continuous process DCS control cabinets
• Thermal power plant boiler, turbine high-reliability control system
• Pharmaceutical, LNG storage, metallurgy critical production lines requiring zero communication outage
• All industrial sites that adopt redundant ControlNet architecture to avoid production shutdown caused by single network failure
