Key Features:
- Dual-Port Flexibility – Independent configuration for mixed-protocol operation.
- Noise Immunity – Opto-isolation and surge protection for harsh environments.
- Hot-Swap Capable – Replaceable without turbine shutdown (redundant systems).
- Protocol Adaptability – Connects to Modbus RTU, DCS, PLCs, and legacy devices.
- Real-Time Diagnostics – LED indicators for data flow and fault detection.
- SIL-2 Compliance – Supports safety-critical communication loops.
Primary Function & Purpose:
Translates serial data between field devices (e.g., sensors, HMIs) and Mark V controller logic. Enables:
- Remote monitoring of turbine parameters
- Integration with plant-wide control systems (DCS/SCADA)
- Trip signal transmission to auxiliary systems
Typical Applications & Use Cases:
- HMI Integration – Connection to operator workstations (RS-232/RS-485 links).
- Protective Relaying – Communication with generator protection devices.
- Sensor Networks – Data acquisition from vibration monitors (e.g., Bently Nevada).
- Third-Party Interfaces – Modbus RTU links to fuel control valves or emissions systems.
- Redundant Control Sync – Cross-communication between TMR processor panels.
Application Fields:
Deployed in turbine control communication networks across:
- Power Generation: Gas/steam turbines in combined-cycle plants (CCPP), nuclear auxiliaries.
- Oil & Gas: Turbine-driven compressor control and safety systems.
- Marine Propulsion: Naval vessel power management.
- Industrial Plants: Cogeneration facilities, paper mills, chemical processors.
