GE IS200JPDGH1A Product Description

The IS200JPDGH1A (alternate revision IS200JPDGH1ABD) is a rack‑mounted JPDG power distribution board for GE Speedtronic Mark VI / Mark VIe turbine control systems. It acts as a central power hub that receives redundant DC input power, then distributes fused, conditioned power to I/O packs, processor modules, network switches and field transmitter loops within the control cabinet. Equipped with diode‑OR redundant power input, onboard branch fuses, fault‑sensing circuits and front‑panel test points, this passive PCB monitors branch power health and feeds fault status signals to paired PPDA I/O modules for system‑level diagnostics. Conformal‑coated hardware variant is available for high‑humidity, high‑vibration power‑plant cabinet environments.

Product Features

• Redundant 28 VDC power input with diode‑OR auctioneering, prevents back‑feeding between independent power supplies
• Multiple fused output branches delivering clean DC power to I/O packs, CPU modules and Ethernet switches
• On‑board fuses for individual circuit protection; fuse‑fault detection feeds status feedback to system controllers
• Multi‑channel expansion ports for daisy‑chaining additional power distribution boards for large‑rack deployments
• Front‑accessible multimeter test points for quick‑field voltage measurement and troubleshooting without disassembly
• Standard plug‑in rack‑mount form factor compatible with Mark VI / Mark VIe backplane infrastructure
• Supports simplex, duplex and TMR triple‑modular‑redundant system architecture configurations
• Conformal‑coated hardware option resists dust, moisture and corrosive air inside power‑plant control cabinets

Application Scenarios

• GE Mark VI / Mark VIe gas‑turbine control cabinet power distribution subsystems
• Steam turbine and combined‑cycle power‑generation plant control racks
• Thermal power‑plant generator control and excitation system auxiliary power routing
• High‑availability TMR turbine safety and emergency shutdown (ESD) control systems
• Captive industrial power‑plant turbine‑generator control retrofits and spare‑part replacement
• Petrochemical and oil‑gas facility turbine‑driven equipment control cabinets
• Large‑scale Mark VIe rack expansion projects requiring multi‑module power‑distribution scaling
