Main Functions

1. High‑speed turbine critical signal acquisition: Receives magnetic pickup (MPU) speed sensor signals for rotor speed measurement and overspeed protection; accepts generator and bus PT voltage inputs for synchronizing‑check logic; also processes flame detector signals, emergency trip contact inputs and main breaker status feedback.More products: www.plcva.com

1. Redundant IONet Ethernet communication: Dual 100 Mbps full‑duplex Ethernet ports implement redundant IONet bus communication. Transmits field‑acquired raw data to Mark VIe main controllers and receives protection‑control commands from host processors with low deterministic latency.
2. Primary turbine protection execution: Executes high‑priority overspeed protection, generator synchronization logic and emergency trip‑related signal processing. Delivers fast‑response trip output signals for turbine safety protection loops, complying with power‑generation safety standards.
3. Galvanic isolation & noise suppression: Built‑in optical and galvanic isolation circuits for field‑side signals, suppresses industrial surge, ground‑loop interference and electromagnetic noise, protects internal module circuits from field‑side electrical damage.plcva.com
4. On‑board hardware self‑diagnosis: Continuously monitors sensor channel faults, communication link status and internal hardware failures. LED status indicators show power, link and channel fault conditions; fault events are logged in system event log for maintenance troubleshooting.
5. Conformal‑coated industrial hardware: PCB conformal coating provides moisture, dust and chemical‑corrosion resistance for cabinet‑mount deployment in power‑plant environments.
6. Modular hot‑swap capable pack structure: Plug‑in I/O pack installation on TTUR terminal board; allows replacement without cabinet power‑down under permitted maintenance conditions, shortening system downtime.
