Functional Features Acquires multi‑channel turbine emergency‑trip and safety interlock discrete contact signals. Receives and processes turbine speed‑pick‑up pulse input signals. Redundant dual‑Ethernet communication guarantees reliable protection‑status data exchange with main controller. 
Application Scenarios Distributed turbine safety‑trip signal acquisition and protection‑logic processing for Mark VIe gas‑turbine and steam‑turbine units. Field‑side safety interlock signal interface for power‑plant turbine control systems.
Structural Characteristics Compact metal‑shielded packaged housing for TS‑35 DIN‑rail installation. Front faceplate fitted with status LED indicators and dual RJ45 Ethernet connectors. Rear power input connector and dedicated cable port for trip‑protection terminal‑board interconnection.
Working Principle Field turbine trip contacts, interlock status and speed‑pick‑up pulse signals are sent to matched trip terminal board and transmitted to IS220PTURH1B.
Installation Requirements Install module on standard TS‑35 DIN‑rail inside designated protection‑related enclosure. Supply stable 28VDC power and strictly comply with polarity requirement. Connect dual Ethernet interfaces to redundant IONet control network. Field protection‑signal wiring adopts shielded cables and separate routing from high‑voltage power cables.
