Description

IS230JPDGH1B GE Mark VIe JPDG Redundant DC Power Distribution Module

 

Product Application

IS230JPDGH1B (JPDG) belongs to GE Speedtronic Mark VIe control system. It is a DIN-rail mounted power distribution unit, receives redundant DC input and splits power into multiple independently protected branch outputs for Mark VIe I/O packs and field terminal assemblies. It monitors branch current and temperature, reports power faults to Mark VIe controller over system communication bus. Widely used in combined cycle power plant gas turbine, steam turbine and generator control cabinets. Works with Mark VIe controller and I/O packs such as IS230PCAAH1B, IS220PHRAH1B etc.

Core Technical Parameters

  • Dual redundant DC power input, can continue operation if one power source fails
  • Individual fuse protection for each output branch, local fault will not take down whole rack
  • Real-time thermal and current monitoring, fault diagnostics uploaded to Mark VIe HMI
  • Conformal coating protects PCB from dust, moisture and corrosive gas in power plant cabinet
  • Compatible with simplex / TMR Mark VIe I/O rack architecture
  • No internal power conversion; it is a power distribution & protection hub, not a power supply

Product Features

✅ Dual Redundant DC Power Input Supports two independent DC feeds, single power source loss will not interrupt power delivery to Mark VIe I/O packs.

✅ Individually Fused Output Branches Each output branch has separate fuse protection; short-circuit on one field branch only trips its own fuse, protecting rest of control rack.

✅ Built-in Power & Thermal Diagnostics Continuously monitors supply health, branch current and module temperature; sends fault alarms to Mark VIe operator HMI.

✅ DIN Rail Compact Installation Standard DIN rail mounting inside turbine control cabinet, simple installation and replacement.

✅ Conformal Coated PCB Conformal coating improves reliability in power plant environments with dust and trace corrosive vapors.

✅ Designed for Turbine Control Critical Application Purpose-built for Mark VIe gas/steam turbine control and generator protection, high availability design for power generation.

✅ Fault Indication LEDs Front panel LEDs show power OK, supply failure, branch fault and over-temperature for fast local troubleshooting.

 

Installation Guidelines

  1. Mount IS230JPDGH1B onto DIN rail inside Mark VIe control cabinet and lock module.
  2. Wire dual redundant DC power sources to module input terminals.
  3. Connect each output branch to Mark VIe I/O packs and terminal boards.
  4. Check branch fuses are correctly rated and seated.
  5. Power on DC supplies; verify front panel power LEDs are normal.
  6. Connect module communication to Mark VIe controller.
  7. Use GE turbine diagnostic software to verify power monitoring and fault reporting.
  8. Perform loss-of-one supply test to confirm redundancy function before commissioning.

 

Maintenance Instructions

Daily Maintenance Check front panel LED indicators; monitor power supply and branch fault alarms on Mark VIe HMI.

Periodic Maintenance (Every 6–12 months) Clean module surface dust and cabinet air filter. Check power terminal lugs for tightness. Inspect fuse integrity.

Fault Maintenance

  • Single DC supply fault: Switch to remaining healthy power source, replace defective upstream power supply.
  • One branch no output: Check corresponding branch fuse and field wiring short circuit.
  • Over-temperature alarm: Inspect cabinet cooling fan and airflow, check for excessive load.
  • Do not replace fuses with higher rated values without turbine control engineer approval.

Long-Term Operation Tips Maintain cabinet temperature within -30~+65℃. Keep spare IS230JPDGH1B and spare fuses. Backup Mark VIe system configuration.
