Description

Hardware & Electrical Specifications

• Model：IS200PMCIH1ABA
• Part Number：IS200PMCIH1ABA
• Module Type：PMCI Processor‑Module Communication Interface Mezzanine Card
• Form factor：Compact PMC mezzanine daughter‑board, plug‑in onto CPU main‑board
• Power supply：+5 V DC supplied by host CPU board, typical power consumption 6 W
• Communication：Dual‑port 100BASE‑TX IONet Ethernet (Port A / Port B); BNC SYNC time‑sync input interface
• Front‑panel：Two RJ45 IONet ports, BNC SYNC connector; ONLN, MOD status LED indicators
• PCB treatment：Conformal coated for dust‑moisture‑corrosion resistance
• On‑board protection：ESD protection, surge suppression, hardware link‑watchdog monitoring circuit
• Compatibility note：Cannot run standalone; must pair with corresponding Mark VIe CPU board; firmware revision must match system configuration; dual‑channel IONet link test is mandatory after replacement。

• Dimension：152 mm × 89 mm × 22 mm
• Connector：High‑density gold‑finger mezzanine connector for CPU mating; front‑panel RJ45 & BNC jack
• Handling note：ESD‑sensitive PCB, anti‑static wrist‑strap mandatory during handling
• Recommended wire cross‑section：Shielded CAT5e twisted‑pair cable for IONet network wiring

Main Functions

1. Act as dual‑redundant IONet Ethernet bridge between main CPU and all I/O packs inside the rack.
2. Transmit field measuring data, protection interlock signals and channel fault diagnostic messages bidirectionally between controller and I/O modules.
3. Distribute high‑precision SYNC time‑synchronization signal to guarantee multi‑I/O‑channel sampling time consistency for turbine fast‑control loops.
4. Hardware link diagnosis for Port A / Port B IONet channels; detect cable break and link‑down abnormality.
5. On‑board self‑diagnosis: detect daughter‑board hardware fault and mezzanine connector poor‑contact, report fault status to main controller.
6. Front‑panel LED status indication:
   • Green ONLN LED：Module power‑on and link normal
   • Yellow MOD LED：IONet bus communication active
   • Red LED：Communication loss / hardware fault alarm

Installation & Wiring Requirements

1. Cut off rack power supply before replacement. Hot‑swap is forbidden. Strict anti‑static protection when handling PCB board.
2. Align and insert PMCI mezzanine board fully into designated CPU board connector, fasten fixing screws to avoid poor contact.
3. Connect IONet network cables and SYNC synchronization cable strictly follow GE Mark VIe wiring manual; separate network cables from high‑power cables to reduce electromagnetic interference.
4. Complete protective grounding according to GE Speedtronic system specification.
5. After replacement: verify dual‑port IONet link status, check SYNC signal quality, download controller configuration, validate full‑I/O‑rack data exchange before commissioning.
6. Replacement note: Confirm firmware version consistency; both A/B channel communication function test must be performed after swap.
