About the IS220YDIAS1A

The IS220YDIAS1A is a Discrete Contact Input I/O module developed by General Electric for use in the Mark VIe Speedtronic control system, designed for gas and steam industrial turbine control. The Mark VIe Series, which includes this module, represents one of the latest and most advanced iterations of GE’s Speedtronic turbine control systems.

The Mark VIe series notably extends the application range beyond gas and steam turbines to include wind turbine automated drive assemblies, marking a significant advancement from the earlier Mark V series.
