Products Description
GE DS200SIOBH1ACA VME Serial I/O Board in stock
GE DS200SIOBH1ACA is a 6U VME SIOB serial I/O board for GE Speedtronic Mark V turbine control system. It acts as the interface between Mark V controller and field serial intelligent devices and discrete signals, equipped with high isolation circuits and conformal coating for harsh industrial cabinet environments.
This board comes with multiple DIP switch blocks and jumpers for hardware configuration, onboard LED status indicator and 40-pin field connector. It is a discontinued legacy component, supplied as surplus or refurbished spare parts for maintenance and retrofit of existing Mark V gas and steam turbine control cabinets.
