Description

GE IS210MACCH1AKH MACS Cabinet Hub Communication Board for Mark VIe / Mark VIeS Turbine Control System

Product Details

The IS210MACCH1AKH is cabinet‑level central communication hub board for GE Mark VIe and Mark VIeS turbine control systems. Origin: USA. Lifecycle status: EOL discontinued, OEM new production stopped; market supply includes NOS surplus and fully‑tested refurbished spare‑parts for power‑plant maintenance.

It acts as bridge between UDH (Unit Data Highway) and IONet distributed I/O network, performs 10/100 Ethernet packet switching for cabinet internal communication. Supports TMR triple‑modular‑redundant R/S/T network paths. Dual redundant 28 VDC power supply input. AKH suffix means conformal‑coated PCB (G3) for corrosive cabinet environment. Equipped with SFP slots for fiber‑optic IONet extension to remote I/O cabinets. On‑board diagnostics monitor cabinet temperature, fan status and power health. Operating temperature: ‑30℃ ~ +65℃. Weight approx 0.65 kg. Hardware revision must match original during replacement.

Applications

‑ Combined‑cycle gas / steam turbine Mark VIe control cabinet core network backbone ‑ Thermal‑power plant, nuclear‑grade Mark VIeS safety‑related system communication ‑ Power‑plant turbine cabinet IONet distributed‑I/O network routing ‑ Petrochemical turbo‑machinery control system spare‑part replacement ‑ Retrofit and component swap for legacy Mark VIe / Mark VIeS racks ‑ Spare inventory for power‑plant turbine‑control maintenance department
