Technical Specifications Module Type: Power‑distribution monitoring packaged I/O Pack Applicable System: GE Mark VIe Speedtronic Turbine Control System Communication Interface: Dual 10/100Mbps RJ45 Ethernet IONet redundant network Field Interface: Connects to matched power‑supply feedback terminal board Power Supply: 28VDC nominal local field power Monitored Signal Type: Multi‑channel AC/DC power‑rail feedback and ground‑fault detection signals Operating Temperature: ‑30 ℃ to +70 ℃ Storage Temperature: ‑40 ℃ to +85 ℃ Relative Humidity: 5%‑95%, non‑condensing Mechanical Dimension: Standard Mark VIe packaged I/O housing, DIN‑rail mountable Certifications: CE, UL power‑generation industrial component compliance
Functional Features Samples multi‑channel power‑supply feedback signals from internal power distribution hardware. Implements ground‑fault detection function for control cabinet power circuits. Redundant dual‑Ethernet communication ensures reliable power‑status data transmission to main controller.
Application Scenarios Power‑distribution signal monitoring for Mark VIe turbine control cabinet power units. Ground‑fault detection and power‑rail health supervision for power‑plant turbine control hardware.
Structural Characteristics Compact metal‑shielded packaged housing for TS‑35 DIN‑rail installation. Front faceplate equipped with status LED indicators and dual RJ45 Ethernet connectors. Rear power input connector and dedicated cable port for power‑feedback terminal‑board connection.
Working Principle Power‑rail feedback signals and ground‑fault sensing signals from power‑distribution terminal board are transmitted to IS220PPDAH1B. Internal sampling circuit processes these signals and converts analog measurement values into digital data.
Installation Requirements Install module on standard TS‑35 DIN‑rail inside control cabinet. Apply correct 28VDC power supply and avoid reverse polarity connection. Wire dual Ethernet ports to redundant IONet control network. Connect dedicated ribbon cable between IS220PPDAH1B and matched power‑feedback terminal board.
