The SELCO SIGMA S6100 S/LS module provides integrated bus bar monitoring, frequency stabilization, voltage stabilization, check/automatic synchronisation and active/reactive load sharing. The S6100 module relies upon the measurements and calculations broadcasted by its partner SELCO SIGMA S6000 IO/P module. The S6000 provides integrated protection, basic I/O and data acquisition. Finally, the S6100 module will operate as an interface between the optional SELCO SIGMA S6600/S6610 Power Manager and the engine related signals (e.g. start/stop, engine fail etc.).
