Description

GE IS210MACCH2A MACS‑2 Cabinet Hub Communication Board for Mark VIe / Mark VIeS Turbine Control System

Product Details

The IS210MACCH2A is second‑generation MACS cabinet‑level central communication hub board for GE Vernova Speedtronic Mark VIe and Mark VIeS turbine safety‑control systems, successor to IS210MACCH1A series. Origin: USA. Lifecycle status: EOL discontinued, no OEM new production; market supply consists of NOS surplus and fully‑tested refurbished spare‑parts for power‑plant maintenance.

It performs high‑speed Ethernet packet switching between UDH (Unit Data Highway) and IONet distributed I/O fieldbus. Supports TMR triple‑modular‑redundant R/S/T network paths. Accepts dual redundant 28 VDC power supply input. Variant IS210MACCH2AKH features conformal‑coated PCB for G3 corrosive cabinet environment. Equipped with SFP fiber‑optic slots for long‑distance IONet extension to remote WETA I/O cabinets. On‑board diagnostics monitor cabinet temperature, fan health and power‑supply status. Operating temperature: ‑30℃ ~ +65℃. Weight approx 0.68 kg. Hardware revision and firmware version must match original during replacement; direct drop‑in replacement for IS210MACCH1 series requires ToolboxST firmware compatibility verification.

Applications

‑ Combined‑cycle gas / steam turbine Mark VIe control cabinet core network backbone ‑ Thermal‑power plant and Mark VIeS safety‑related protection system communication infrastructure ‑ Power‑plant cabinet‑internal IONet distributed‑I/O network routing, connect WETA remote I/O cabinets ‑ Petrochemical turbo‑machinery control system spare‑part replacement and cabinet upgrade ‑ Retrofit & component swap for legacy Mark VIe / Mark VIeS racks (upgrade from MACCH1A hardware) ‑ Spare inventory for power‑plant turbine‑control maintenance department

Main Functions

1. High‑speed Ethernet switching and deterministic real‑time data routing between Mark VIe main processors and IONet I/O packs / WETA controllers.
2. Acts as bridge between UDH unit‑level highway and cabinet‑internal IONet network for gas‑steam turbine control architecture.
3. Supports TMR triple‑modular‑redundant network path operation for safety‑related turbine protection logic.
4. SFP fiber interfaces extend IONet bus to remote distributed‑I/O cabinets, reduces expensive long‑distance field instrument cabling.
5. Monitors cabinet environmental conditions and power‑supply health, pushes fault and warning events to turbine operator HMI and historian.
6. Conformal‑coated variant ensures stable long‑term running under harsh plant cabinet atmosphere.
7. Cooperates with CPU packs, WETA units and various IONet I/O modules to build complete Mark VIe distributed turbine‑control hardware system.
8. Serves as second‑generation central network backbone hub inside GE Mark VIe / Mark VIeS turbine control cabinet.
