The GE IS200TPROH1C is an Emergency Protection (TPRO) terminal board, a critical component in turbine safety systems, designed to interface with PPRO I/O packs for emergency protection in simplex and TMR (Triple Modular Redundancy) applications. Housing three PPRO I/O packs, it conditions speed signals, processes bus/generator voltage inputs via two potential transformers (PTs), and facilitates connections to backup trip relay boards through three DC-37 pin connectors.
Equipped with two pluggable 24-barrier terminal blocks, it supports speed signal and PT input wiring and features removable Euro-Block terminals for easy maintenance. Mounted on a DIN-rail or panel via a sheet metal carrier with a plastic insulator, it ensures secure installation in industrial environments. Key operational elements include nine speed inputs, P24 output with a MARET return, and 4-20 mA inputs for future extensions.
Features:
Protection Integration: Interfaces with three PPRO I/O packs or simplex setups, conditioning speed signals and voltage inputs for emergency turbine protection.
Connectivity: Three DC-37 connectors link to backup trip relay boards; barrier terminals support speed/PT wiring, with removable blocks for easy maintenance.
Voltage Safety: Critical warning against cross-connecting 240V AC and DC, as peak voltages exceed MOV ratings; 120V AC applications are safe for MOVs.
Performance Metrics: Supports magnetic speed pickups with pulse rates from 2 Hz to 20,000 Hz and 0.05% accuracy, ensuring precise speed monitoring.
Diagnostics & Configuration: Scans electronic ID parts on startup to verify hardware configuration; jumpers adjust for thermocouple or 4-20 mA inputs.
Environmental Durability: Surface-mount technology and operating temperature range of -30°C to 65°C ensure reliability in harsh industrial settings.
Power Resilience: P24 output, derived from ORing 28V supplies of R/S/T I/O packs, remains accessible even if individual packs are offline.
