GE Speedtronic Mark VI and Mark VIe turbine control hardware — IS200, IS220 and IS420 series I/O, controllers and terminations.

The Speedtronic line is GE's turbine control platform, and the Mark VI (IS200-series hardware) and Mark VIe (IS420 and IS220 distributed I/O) generations still govern a large share of the world's installed gas and steam turbines. These systems protect and sequence the turbine itself — fuel control, trip logic, vibration monitoring — so their boards and I/O packs are maintained with the same rigour as the machines they protect.

The IS200, IS215, IS220, IS400 and IS420 references indexed here cover I/O boards, terminal boards, controllers and network modules across both generations. Product pages record board functions, connectors and compatibility from the original documentation; the sourcing guidance reflects how tightly Mark systems couple hardware revision to turbine firmware, which makes revision matching the central procurement check.
