GE 151X1235BC01SA01 | EX2100E controller

The 151X1235BC01SA01 is an integrated combined UCSB‑CSLA controller unit developed for GE Mark VIeS turbine control and EX2100e generator excitation systems. Running QNX Neutrino 

real‑time multitasking operating system, it undertakes core logic computation, control algorithm execution and high‑speed serial link expansion tasks. This controller communicates with field I/O 

modules via dedicated IONet industrial network, without carrying local I/O channels itself. It supports SIL2‑SIL3 safety‑related loop processing for power generation equipment. Widely deployed in 

thermal power plant, combined‑cycle unit generator excitation cabinets and steam/gas turbine control racks, it acts as a vital replacement spare for on‑site unit overhaul and fault repair.
